DHS Announces First Department-Wide Policy on Body-Worn Cameras | Homeland Security

They just about need cameras for backup when criminals lie.

The more they're used, the fewer the false lawsuits will end. Double upside- not only will evidence from these cameras scuttle fake lawsuits, it will bolster the Reality of an overwhelming majority of Officers as guiltless of any wrong doing.
For those arrested properly try to file false suits, it should go on their record as well that they file a false claim(s) against innocent police officers.
