Some cops in my view are cowards that like to prey on petty criminals. Very few go after big bosses or politicians (Maybe because they sign the checks?).
I do feel that many cops get into law enforcement for the wrong reasons such as to justify looking for trouble for a quick adrenaline rush. I know cops that would find a reason to pull a car over just because they do not like the look of the driver but hey, what can you do.
There are a lot of knuckle heads in the populace though that really like to stay in trouble. I think having to deal with this element frustrates some cops and makes them seem like jerks in general. Maybe it is time to go looking for new work once that happens.
