not all cops = pigs
there are plenty of times where the multiple cops in my family have almost not made it home due to assholes taking a stab litterally, driving crazy, etc.
There are idiots everywhere. A lot of people who ARE police, probably shouldn't be. There is probably a lot more psychological testing that should be done on a regular basis, because any normal person would have had a gut full of uncivilized behavior in a very short amount of time... Maybe this guy really isn't cut out for it.
There are a lot who are though, and deal with a lot every day, for not so much money. Try spending a real week in homocide, seeing messed up bodies and having to tell people their/hwatever is dead.. or on the road watching car after car do the same fucked up thing and kill people, or special ops and put yr life on the line for people who call you a pig.. maybe don't generalise.
