The Knock-and-Talk: Why Agents Show Up Without a Warrant.

A knock-and-talk does not require a warrant. No judicial approval is required before government agents can walk up to your front door and try to talk to you. During a knock-and-talk, agents are typically trying to accomplish one of two goals. The first goal is generally to obtain voluntary conversation, voluntary entry, voluntary consent, or other voluntary investigative information. The second goal, if they don’t get what they need the first way, is to develop probable cause.

It is quite common for agents to conduct a knock-and-talk before they have developed enough probable cause to obtain a search warrant. If the knock-and-talk is successful, then that’s all the agents need. If it’s unsuccessful, then the information that the agents gleaned during the knock-and-talk (or the reasons why the knock-and-talk was unsuccessful) might be the exact things the agents need to convince a magistrate judge that issuing a search warrant is warranted in this case.

Generally, residents are not required to open their doors when government agents initiate a knock-and-talk, provided the agents do not enter before they get consent. While you have the right to refuse consent for entry, there is no general requirement that you must open your door when agents attempt to conduct a knock-and-talk.

Does the Fourth Amendment protect common apartment hallways? This is a more complex question. It depends on whether the apartments building has access controls (like security guards or gated access) and what case law has established within your jurisdiction. In some cases, agents can enter apartment building hallways without any justification, and in some cases, agents can be kept out of apartment building hallways.

Why Does the Law Let Agents Approach My Front Door?

In Florida v. Jardines, the Supreme Court recognized the customary license of a visitor to approach the front door of a residence. This customary license is an implied license that protects a visitor from prosecution for trespassing. Importantly, the Supreme Court’s opinion in Florida v. Jardines also made clear that the scope of this implied license is limited not only to a particular area but also to a specific purpose, so conduct that objectively reveals a purpose to search the home falls outside it. As Florida v. Jardines explains:

“Visitors have a customary license to approach a home’s entrance, knock or ring the doorbell, and wait briefly for a response.”

The Supreme Court noted that this implied license generally permits:

• Approaching the home entrance
• Knocking or ringing the doorbell
• Waiting for a reasonable amount of time to see if the occupant answers
• Departing the home’s entrance if the occupant does not answer

Notably, a visitor’s investigative purpose is not enough to alone invalidate a customary doorstep approach. If an officer wants to get the attention of a home’s occupant, the officer can walk up to the front door and knock. To avoid criminal trespass, a law enforcement officer just needs to do no more than a typical visitor would do. He must:

• Approach the front door by an ordinary route that a visitor would take
• Wait long enough for the occupant to respond (but not so long as would normally alert the occupant to his investigative purpose)
• Depart if the occupant does not answer or declines to speak to him

If agents are able to have a conversation with the occupant, and the conversation leads to the agents securing access to the residence or obtaining other information, then the agents’ attempt to conduct a knock-and-talk has been successful. As the court explained in United States v. Santana:

“Any search or seizure of a person who has exposed himself to public view by standing in the doorway of his house, not yet inside, is a search or seizure of a person in a publicly exposed place, and the location of the house is not the deciding factor.”

Where Does a Knock-and-Talk Become an Illegal Search?

The implied license discussed in Florida v. Jardines does not authorize agents to linger or explore around the property. In Jardines, an agent who brought a drug-detection dog to the front porch of a home for the purpose of sniffing the home’s threshold exceeded the scope of the implied license. The Supreme Court described the agent’s use of the drug-detection dog as a search, noting that the Fourth Amendment protects both the home and the curtilage surrounding the home. By bringing the dog to the home’s front porch, the agent invaded the homeowner’s “constitutionally protected area” in order to gather evidence through a warrantless search.

Generally, a locked gate acts as a physical barrier that withdraws permission for anyone to proceed past the gate like an ordinary visitor. If agents enter a property past a locked gate without permission, they are conducting an illegal search.

No-trespassing signs can also withdraw implied access to a home’s front door. Whether a no-trespassing sign defeats a knock-and-talk is unsettled, and some courts have upheld the approach anyway, in United States v. Carloss, 818 F.3d 988 (10th Cir. 2016), the Tenth Circuit held that signs posted around the house and on the front door did not revoke the officers’ implied license to knock. However, the effect of no-trespassing signs on implied license for knock-and-talks is nuanced. Some aspects of their effectiveness vary based on:

• The wording of the sign;
• The placement of the sign;
• The location of the sign;
• Whether the sign is posted on a fence or a gate; and,
• Whether the sign explicitly prohibits officers from trespassing on the property.

If you are thinking of posting a no-trespassing sign, the effectiveness of that sign in preventing a knock-and-talk depends on your specific circumstances, including:

• The wording of the sign;
• The placement of the sign;
• The location of the sign;
• The type of structure the sign is posted on; and,
• Whether the sign is targeted toward law enforcement officers.

In cases where the law is unsettled, officers typically will do whatever they can to try to use a knock-and-talk as a viable investigative tool while avoiding any consequences of an illegal search.

What do knock-and-talks have in common with residential search warrants?

How do I know if agents are detaining me?

Although federal agents and other law enforcement officers may start their encounters with civilians politely, their persistent, repetitive, or coercive conduct can transform a consensual encounter into a seizure. A seizure occurs when, in the words of the United States Court of Appeals for the Sixth Circuit, “a reasonable person would feel forced to obey law enforcement officers’ requests to stop, remain in a specific location, or otherwise comply with their directions.”

How can you tell if a consensual encounter has become a seizure? Law enforcement agents may display their weapons, order you not to leave, block exits, or retain your identification. These actions all serve to send the message that your “consent” to speak to law enforcement officers is not voluntary.

In determining whether home occupants feel free to terminate their encounters, courts consider all relevant circumstances. Timing may play a role, it is much harder to establish voluntary consent at 3 a.m. than at 10 a.m. The number of agents present will also be important. A dozen federal agents standing on a front porch conveys a far different message than a single undercover officer in civilian clothes. Agents’ tone and positioning will be relevant as well. If agents stand in a way that blocks a front door, this serves to further intimidate the home occupant, and it also makes it clear that the occupant cannot leave.

Generally speaking, if you are talking to federal agents and you are not under arrest, you do not have any federal obligation to identify yourself. However, it is important to understand when you do have to give identification. For example, in the case of Hiibel v. Sixth Judicial District Court of Nevada, the Supreme Court held that:

• If an officer has the authority to conduct a “Terry stop,”
• And if the relevant state law requires an individual to identify himself in such cases,
• Then failure to provide identification may justify an arrest for obstructing a public officer.

The legality of compelled identification is a complex issue involving the Fourth Amendment and the Fifth Amendment. Whether you must identify yourself depends on a wide range of factors including:

• Whether you have been stopped;
• The legal justification for the stop;
• Whether you are in custody;
• The wording of any relevant state law; and,
• Whether the agent is armed and the location of the stop.

Ultimately, the effect of state law on your obligation to identify yourself will depend on the specific facts and circumstances involved. If you have questions about your legal obligations, you should reach out to a lawyer.

Can agents enter or search because I opened the door?

I. I Open the Door; Can They Enter?

Opening the front door does not authorize government agents to enter. Generally, government agents need either a warrant or consent to enter. Consent allows for a warrantless search when, as in Schneckloth v. Bustamonte, “consent is voluntarily given.” The Supreme Court noted that voluntariness “is a fact-specific inquiry that must be determined by all the surrounding circumstances.”

In other words, to prove that consent is voluntary, the government must prove that law enforcement agents used no force, threats, coercion, or other methods that would make a person’s consent involuntary. In Bumper v. North Carolina, 391 U.S. 543 (1968), the court affirmed that a person’s consent to search would not be voluntary if obtained:

• Following threatened force or force;
• By using force;
• By making deceptive or false claims of legal authority;
• Through other forms of illegal or improper law enforcement tactics; or,
• After being deprived of the legal right to legal representation.

It is important to understand that even if agents have been polite so far, this does not mean that they intend to be polite in the future. If agents suspect a crime has been committed, they may try to intimidate or coerce you or your family members.

II. I Consent; What Then?

The fact that you consent to a warrantless search does not mean that law enforcement agents have “carte blanche” to enter and search your home. It may be important to understand when consent should be limited in order to protect your privacy. Even in situations where you consent to some aspect of a warrantless search, you can either:

• Limit the search to specific rooms;
• Limit the search to specific objects;
• Limit the search to a specific purpose; or,
• Withdraw your consent before law enforcement officers finish their search.

Residents have no obligation to consent to law enforcement agents conducting a warrantless search. There is no general obligation for homeowners to open their doors to government agents or allow government agents to enter. It is also the case that homeowners are not generally required to let government agents search for any reason.

Wait, so, what if a co-occupant consents to enter? In some cases, if a co-occupant has “common authority” over the property in question, the co-occupant may consent to a warrantless search of shared-use space. In other words, if a co-occupant has legal authority to deny entrance to others, this is not normally enough to establish common authority for a warrantless search.

What if both co-occupants are present? If both co-occupants are present and one objects to a warrantless search, the objection will trump the co-occupant’s consent. The objecting co-occupant must be “physically present” to defeat the other co-occupant’s consent. Once the objecting co-occupant leaves, the other co-occupant may then give consent.

What should I say if agents start asking questions?

Do I Have the Right to Remain Silent?

Generally, the right to remain silent that you hear in Miranda warnings only applies to custodial interrogation. Miranda warnings are not required before ordinary doorstep questioning. Voluntary statements made to federal agents in a noncustodial setting can be used as evidence against you.

Do I Have the Right to a Lawyer?

The Sixth Amendment right to counsel generally attaches only after formal prosecution begins. Requesting an attorney during a noncustodial encounter does not automatically bar law enforcement agents from continuing their investigation or asking questions at a later date. However, this still does not mean you have to speak with federal agents. You have no obligation to speak with federal agents voluntarily and you should speak to your own lawyer.

Are Federal Agents Allowed to Lie to Me?

To a large extent, federal agents are allowed to use deception when conducting a knock-and-talk. This is because agents are generally allowed to do whatever is necessary to achieve an investigative goal, as long as it does not violate a suspect’s constitutional rights. Although agents’ use of deception may undermine whether consent is voluntary, deception can generally be used.

Is it a Crime to Lie to Federal Agents?

It is a crime to knowingly and willfully make false material statements to federal agents. Under 18 U.S.C. Section 1001, it is a crime to:

• Falsify, conceal, or cover up a material fact;
• Make a materially false, fictitious,

What happens if I refuse consent or questions?

If law enforcement agents show up at your home for a knock-and-talk and you choose not to answer questions, they have to leave. If you have already answered questions but then you decide to end the encounter, you can do that too. You can end your conversations with law enforcement agents, decline to answer any further questions, and close your door.

Notably, the fact that you refuse to answer agents’ questions or let them in to search your home does not establish probable cause. While a prior refusal does not categorically bar agents from attempting a consensual approach to your home at a later date, it may deter agents from returning to your home.

Even if you refuse consent for a warrantless search, this will not prevent law enforcement agents from using other (and perhaps more invasive) investigative tools. For example, agents may be able to conduct surreptitious surveillance, issue subpoenas, interview third parties, and pursue other investigative avenues that do not require you to consent.

Wait, doesn’t this mean that if agents don’t find the information they need through a knock-and-talk, they will just obtain a search warrant? In some cases, this is true. However, if agents do not obtain your consent to enter your home, then agents must develop enough probable cause to convince a magistrate judge to grant a search warrant. While agents may obtain a search warrant using information they gleaned from a knock-and-talk, agents will not be able to obtain a search warrant based solely on your refusal to consent. Any search warrant would need to be based on independent evidence that meets the legal requirements for granting judicial authorization to enter.

How is this different from a warrant or no-knock raid?

I. What is a Search Warrant?

A search warrant is a court order issued by a magistrate judge that requires a third party to undergo a search of a residence, business, vehicle, boat, aircraft, or other property. To obtain a search warrant, law enforcement agents must establish probable cause, i.e., a substantial basis for suspecting that the evidence or contraband sought will be found at the specified location, supported by an oath or affirmation.

While agents who obtained a search warrant can compel access to the location or area to be searched, obtaining a search warrant does not authorize agents to compel answers to any investigative questions. In Bumper v. North Carolina, 391 U.S. 543 (1968), the U.S. District Court for the District of Colorado noted that the scope of a search warrant issued for “all evidence and items and fruits of crimes and criminal violations,” “all records, journals, all books and all papers,” and “all documents” was limited to searching “all offices and all living quarters.” Importantly, this gave agents no authorization to “conduct a search and seizure of all documents in any particular computer” in the search area.

II. What are the procedural requirements for executing a search warrant?

Pursuant to Federal Rule of Criminal Procedure 41(e)(2)(A), an officer executing a search warrant must:

• Provide a copy of the search warrant to the person whose property is being searched; or,
• Leave a copy of the search warrant with the person whose property is being searched if this is not practicable.

In addition, Federal Rule 41(e)(2)(B) requires officers who execute a search warrant to make a complete inventory of any property seized and to “leave a copy of the receipt with the person from whom the property was seized or at the place where the property was found.”

Notably, Federal Rule 41 does not require law enforcement agents to display a search warrant to the occupants of the search location before beginning its execution. In United States v. Grubbs, the Supreme Court rejected the idea that there is a constitutional requirement to “present a copy of the search warrant to the occupants of the place to be searched prior to execution.”

III. What is the difference between a knock-and-talk and a knock-and-announce search?

A knock-and-talk is a consensual doorstep encounter between homeowners and law enforcement agents. It is not the same as a “knock-and-announce” search. The latter is the procedure that law enforcement agents use to execute a search warrant when they have no reason to believe that they have enough justification for a “no-knock” search. In Richards v. Wisconsin, the Supreme Court affirmed that law enforcement agents need not follow the knock-and-announce procedure if there is reasonable suspicion to believe that a “no-knock” search is justified under one of three circumstances:

• The threat of violence;
• The futility of knocking; and,
• The imminent risk of evidence destruction.

When a magistrate judge issues a search warrant, the magistrate will also determine whether a no-knock search is warranted based on the justification set forth in the agent’s affidavit. If the agent has developed sufficient probable cause and justification, the agent will likely be authorized to execute a no-knock search.
