Some truth to that. They know the politicians will throw them under the bus at the first opportunity.
Not just the pols. It's gotten so if the families of the "victims" stay outraged, they'll get settlements of millions of dollars, even when the police action is justified. They just have to stay outraged enough and get a few marches and protests going.
The police have to be thinking of the hassle they'll go through, for years and maybe forever, even with a justified shooting.
Spot on, that.
