Well being involved with law enforcement for the last twenty years of my life, cops that pull people over, 90% of them deserve it, because they were breaking the law. Patrolman do their job right and that's to protect and serve the streets. They aren't detectives that actually work cases like what you stated on beating wives, etc.. That's more of their jobs not patrolmans jobs, can they work it well yea but that's why they have detectives and violent crime units and such. My dad has been in law enforcement for twenty years and I had a uncle that shot in the line of duty. I respect cops. BUT there are some that take their job to seriously, most cops give you 5 mph over or mor3 depending. I will agree with you there about writing tickets for a 42 in a 40 or such like that. But if you're breaking the law, you're breaking the law..
That's just my opinion.
