Most police officers (59 percent) support banning no-knock warrants, like the one that led to the March killing of Breonna Taylor in Kentucky, and restricting chokeholds (68 percent), such as those that led to the death of Floyd this year in Minneapolis and Eric Garner in New York City in 2014.

Most police also back allowing officers to be sued for actions performed on the job — effectively ending qualified immunity, the legal doctrine that shields them from liability — along with other reforms that target their contracts, such as preventing police departments from paying officers on administrative leave during an investigation following the use of deadly force or expunging records of past misconduct.

Broad support also exists for preventing the use of quota systems for tickets and arrests, and compared with the overall electorate, officers are 9 percentage points likely to get behind a ban on the sale of military weaponry from the federal government to local departments that have been deployed in response to demonstrations protesting police violence.
