As members of federal law enforcement, we have a shared obligation to lead by example in a
way that engenders the trust and confidence of the communities we serve. As part of that
obligation, we are updating our Department of Justice policies on certain physical restraint
techniques and on the execution of certain types of warrants.
In the wake of a number of recent tragedies, law enforcement around the nation is reexamining
the way it engages with individuals who come into contact with the criminal justice system. The
Department of Justice has undertaken a similar review and determined that the Department did
not have consistent written policies across its law enforcement components on the use of
"chokeholds" and the "carotid restraint" technique to subdue resisting suspects, or on the use of
"no knock" entries when executing a warrant. Therefore, I am directing the Department's law
enforcement components to revise their policies to explicitly prohibit the use of chokeholds and
the carotid restraint technique unless deadly force is authorized, and to limit the circumstances in
which agents may seek to enter a dwelling pursuant to a warrant without complying with the
"knock and announce" rule.

Chokeholds and Carotid Restraints
The use of certain physical restraint techniques - namely chokeholds and carotid restraints - by
some law enforcement agencies to incapacitate a resisting suspect has too often led to tragedy.
Chokeholds apply pressure to the throat or windpipe and restrict an individual' s ability to
breathe. The carotid restraint technique restricts blood flow to the brain causing temporary
unconsciousness. It is important that Department law enforcement components have an
articulated policy in this area because these techniques are inherently dangerous.
It is a long-standing Department policy that " [l]aw enforcement officers and correctional officers
of the Department of Justice may use deadly force only when necessary, that is, when the officer
has a reasonable belief that the subject of such force poses an imminent danger of death or
serious physical injury to the officer or to another person." Policy Statement Use of Deadly
Force, Approved by the Attorney General July 1, 2004. Given the inherent dangerousness of
chokeholds and carotid restraints, and based on feedback from our law enforcement components
on these techniques, Department law enforcement agents and correctional officers are hereby
prohibited from using a chokehold or a carotid restraint unless that standard of necessity for use
of deadly force is satisfied. Accordingly, Department law enforcement components will revise
their policies to reflect this guidance prohibiting the use of chokeholds or carotid restraints by
Department law enforcement agents and correctional officers, including federal task force
officers, unless deadly force is authorized. Component heads will also ensure that personnel
receive notice of this policy and that it is appropriately incorporated into training.

"No Knock" Entries
Federal agents are generally required to "knock and announce" their identity, authority and
purpose, and demand to enter before entry is made to execute a warrant in a private dwelling.
U.S. Const., amend. IV; 18 U.S.C. ยง 3109; see Hudson v. Michigan, 547 U.S. 586 (2006). Once
that announcement is made, agents must wait a reasonable amount of time based on the totality
of the circumstances to permit the occupant to open the door before making entry into a
dwelling. See United States v. Banks, 540 U.S. 31 (2003). The Supreme Court has recognized,
however, that there are certain situations where it is not constitutionally necessary to "knock and
announce" before entering a dwelling- namely, where the officer has reasonable grounds to
believe that knocking and announcing would create a threat of physical violence, likely result in
destruction of evidence, or be futile. See Hudson, 547 U.S. at 589-90. Because of the risk posed
to both law enforcement and civilians during the execution of "no knock" warrants, it is
important that this authority be exercised only in the most compelling circumstances.

Today, I am announcing that law enforcement agents of the Department of Justice, including
federal task force officers, will limit the use of "no knock" entries in connection with the
execution of a warrant in the following ways.
First, an agent may seek judicial authorization to conduct a "no knock" entry only if that agent
has reasonable grounds to believe at the time the warrant is sought that knocking and announcing
the agent' s presence would create an imminent threat of physical violence to the agent and/or
another person. Prior to seeking judicial authorization for a "no knock" entry, an agent must first
obtain approval from both the Criminal Chief of the relevant U.S. Attorney' s Office (or a Deputy
Chief in a Main Justice litigating component) and an Assistant Special Agent in Charge or Chief
Deputy Marshal in the district. Once judicial authorization is obtained, agents may proceed
without "knocking and announcing" their presence unless they learn of facts that negate the
circumstances that justified this exception to the "knock and announce" rule.
Second, if an agent did not anticipate the need for a "no knock" entry at the time the warrant was
sought, the agent may conduct a "no knock" entry only if exigent circumstances arise at the
scene such that knocking and announcing the agent' s presence would create an imminent threat
of physical violence to the agent and/or another person. If the agent relies on this exigentcircumstances exception in executing the warrant, the agent shall immediately notify his/her
Special Agent in Charge or United States Marshal and provide written notice to the United States
Attorney or relevant Assistant Attorney General.
Because this policy limits "no knock" entries to instances where there is an imminent threat of
physical violence, it is narrower than what is permitted by law - for example, agents must
"knock and announce" even when they have reason to believe that doing so could result in the
destruction of evidence. In setting the policy this way, the Department is limiting the use of
higher-risk "no knock" entries to only those instances where physical safety is at stake at the
time of entry. Should an exceptional circumstance arise (e.g., in a national security matter)
where no imminent threat of physical violence is present but an agent believes the evidence is so
significant, and the risk of its destruction so pronounced, that a "no knock" entry is warranted,
judicial authorization for a "no knock" warrant can be sought if approval is first obtained from
the head of the law enforcement component and the United States Attorney or relevant Assistant
Attorney General, with notice provided to the Office of the Deputy Attorney General.

Policy Revisions by Department Law Enforcement Components

The Department's law enforcement components shall immediately revise their policies to reflect
this guidance prohibiting the use of chokeholds and the carotid restraint technique unless deadly
force is authorized, and limiting "no knock" entries. Law enforcement component heads shall
also report quarterly to the Deputy Attorney General regarding the number of "no knock" entries
their agency executed during the prior quarter.
