"Chokehold" is a generalized term used for a grappling hold that prevents either air (choking) or blood (strangling) from passing through the neck to the brain.
On June 8 the Los Angeles Police Department suspended use of the "carotid restraint control" until the police commission conducts a review of department policy.
The practice had been banned in Los Angeles in the early 1980's after several cases of police brutality, particularly towards minorities, but was reintroduced and taught in police academies in the 1990's as a "less dangerous form of subduing unruly suspects than blows with a club." A Los Angeles department survey at the time showed that 92% of officers wanted the option.
