Los Angeles was at the national vanguard of anti-gang policing, which had more in common with the practices of the US Army than with the protocols of other police forces across the country. This “wasn’t policing,” according to one historian. It was “anti-insurgency run amok.” The idea was to uproot gang members from their strongholds; if that meant decimating whole neighborhoods that gangsters shared with working-class people of color, the collateral damage could be justified in the broader war against crime.
