In general no, I haven’t changed my mind. However, in this particular case with the audio evidence, the individuals involved need to be prosecuted. This one incident does NOT mean ALl policemen and women are that bad. To generalize to that degree is anarchy.
Not all citizens are bad, but ALL cops treat them that way until it is proven otherwise.
I say, what's good for the goose is good for the gander.
Since ALL cops approach citizens as if they were murderous perps, then IMO, ALL cops are lying goons who should not be trusted to do the right thing, much less uphold the law.
