In the years leading up to George Floyd’s death with his neck beneath the knee of a Minneapolis policeman, at least 58 people lost consciousness after the city’s officers put them in neck restraints, according to a CNN analysis of use of force data from the police department.

Officers used neck restraints on 428 people since 2012, and 14% lost consciousness, the data showed. That means the procedure, which is restricted or banned in many large police departments around the country, was used an average of about once a week in the city over that time period.
About two-thirds of the people placed in neck restraints by Minneapolis officers were black — in a city where black residents make up 19% of the population, according to Census data.
Use of force experts told CNN that the procedure that officer Derek Chauvin used — pressing his knee into the back of Floyd’s neck for several minutes, as Floyd groaned that he couldn’t breathe — wouldn’t qualify as a proper neck restraint under the city’s policy and procedure manual.
But the Minneapolis department does allow officers to compress “one or both sides of a person’s neck with an arm or leg, without applying direct pressure to the trachea or airway,” according to a section of the manual that is marked as last being updated in 2012. It calls the method a “non-deadly force option.”
