Fair or ineffective? Police say Pittsburgh’s internal affairs arm is thorough. Activists see little result.

Last year, Pittsburgh police reported that subjects resisted arrest 549 times, prompting officers to engage in hundreds of forced handcuffings and takedowns, 100 Taser shocks, 59 punchings and 31 knee strikes. They used pepper spray 25 times, impact weapons seven times, police dogs six times and their guns four times. Meanwhile, the city’s internal affairs unit, the Office of Municipal Investigations [OMI], handled 27 complaints related to use of force.
