This exactly. Really tough and often thankless job. As shown in Rialto everybody wins when the police wear cameras. Complaints down 88%, use of force down 60% http://www.theguardian.com/world/2013/nov/04/california-poli...
Which really just shows how much better cops behave when they know they're being watched and justifies complaints about their corruption.
Many of the people who deal with police on a frequent basis are skilled liars. They know how to stymie investigations by tying the officers up in paperwork. Having video evidence would prevent spurious complaints.
Fair point. However, I was a cop, and I know better than to trust cops.
That's great too! Win-win!
