Neck restraints, or neck holds, refer to the practice of officers using their arm or leg to restrain someone's neck. The technique has been a subject of controversy for years, particularly following the death of Eric Garner in 2014 after a police officer was accused of choking him.
The term "chokehold" is often used in mainstream discourse to refer to any neck hold, but police generally categorize neck restraints in two ways: the stranglehold and the chokehold. Strangeholds -- also called carotid restraints, sleeper holds or blood chokes -- temporarily cut off blood flow to the brain and are meant to render a subject unconscious for a time. Chokeholds -- also called airway holds -- restrict breathing by applying pressure to the windpipe.
Law enforcement officers say the techniques are used to gain control of aggressive or resisting subjects. Some departments state that they should only be employed as a last resort, when the officer believes the subject poses a threat to their or others' lives. But as the cases of Floyd, Garner and others have shown, neck restraints have the potential to go badly wrong -- sometimes resulting in death.
Here are some of the cities, states and countries that are banning police neck restraints.
The French government announced on Monday that police will no longer be able to use chokeholds when arresting people.
