The Allegheny County District Attorney called for an increase in the use of video cameras in law enforcement Monday.
Stephen Zappala said cameras add an extra level of objectivity to the police force.
Zappala said video cameras in police vehicles reduced legal complaints against police officers across the county by 90 percent.
“Every time that somebody sues a municipality on a one-on-one stop,” he said, “it costs us money as taxpayers. We refer to it legally as contingent liabilities … When you introduce objective evidence, that changes substantially.”
