If cops won't so obsessed by speeding drivers, drunk/disorderly/drugs/guns/knives/fights wouldn't be a problem. Also accidents might get attended to slightly quicker. I was a crash passenger and waited half an hour for a cop to turn up.
People also might have more respect for cops as well if they weren't like the above. A family friend became a cop and turned into a k*ob; even nearly pinching his own bro for speeding.
