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.
Interior Minister Christophe Castaner said the use of chokeholds -- which he described as applying pressure on an individual's neck or throat while holding them on the ground -- was a "dangerous method" and will no longer be taught in police training.
"I hear the criticism, I hear a powerful cry against hatred," said Castaner, referring to large Black Lives Matter protests that took place in several major French cities last week. He added "racism has no place in our society, not in our Republic."
The move came after more than 23,000 protesters took the streets on Saturday to call for an end to police violence, according to Interior Ministry figures released Sunday.
An executive order now prohibits Connecticut State Police from using chokeholds, Gov. Ned Lamont announced Monday.
The order requires the state's Department of Emergency Services and Public Protection to update a state police manual to require troopers to, when possible, deescalate situations, provide a verbal warning and exhaust "all other reasonable alternatives" before resorting to deadly force.
Troopers will also be required to intervene to stop and report another officer's excessive force.
Gov. Gavin Newsom directed police departments last week to stop training officers to use carotid holds, calling the technique "a strangle hold that puts people's lives at risk."
Carotid restraints are performed by compressing the sides of the neck to restrict blood flow to the brain and render a person unconscious.
