Ha! That's a laugh. I'm a retired cop and I know how things work. I don't care what you do for a living. The truth is, everyone's personal life has an effect on the way they do their job. I would hardly call a cop who gave you an equipment violation after having a fight with his wife "immoral". I would say he's just doing his job.You did ,after all, commit the violation. What I would also say is that cops are not mindless automatons who react the same way,in any given situation, day in and day out. Whether you like it or not your chances of getting a ticket for the same violation, from the same cop, vary from day to day depending on his mental state. He may have been notified that he is about to be promoted and is on the top of the world,at peace with everyone. He may also have received news that his child has a terminal disease. You have no way of knowing beforehand and it's unlikely he will confide in you afterward.
What it boils down to is this, tickets are a hassle. No one likes to get them and I rarely enjoyed giving them, but it was my job.(Okay,Yes, I'll admit it, there were some dirtbags I really enjoyed giving tickets to) In an average day of patrol a cop sees many more violations than he can possibly issue tickets for. . Some violations, like equipment violations are obvious. Others, like speed and stop signs are often judgement calls. My personal preference was always for aggressive drivers because I considered them the most dangerous. If you want to avoid a ticket don't commit obvious violations and call attention to yourself. A motorcyle with loud pipes is more likely to get a speeding ticket than one with a quiet exhaust. Do you get my drift?
