Official report condemns police gangs within Los Angeles Sheriff's Department

Gangs within the Los Angeles Sheriff's Department are a "cancer" on the county's law enforcement, says a 70-page report by the Civilian Oversight Commission's special counsel. Wikipedia has a list of the gangs.

The report by the Civilian Oversight Commission condemned the groups, whose members engage in "egregious conduct" like using excessive force and threatening colleagues, as a "cancer" that must be banned immediately.
