In a statement issued by Deputy Attorney General Lisa Monaco, the department said it would be banning the use of chokeholds and carotid restraints by law enforcement officers, except in circumstances where “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.” The department is also banning no-knock warrants, except in situations where an officer believes that announcing their identity could lead to physical harm.
