A couple of my former players are cops here in MD. They will say a lot of it is what happens when they run your tag/license. Also through dealing with them for 4 years I can say that one of them is an ahole and the other isnt.
The one who is an ahole said he writes about 3 times the tickets that the other does and he generally lets good looking women off with a warning.
BINGO!
If an a-hole pulls you over, its a ticket no matter what. The area, region, state, locality, etc. has a lot to do with it from our experience.
In PA, the cop to driver ration is about 1/3 that of Ahia. We drove for over 30 years in PA and I was pulled over twice, my wife, never.
In Ahia, in just 10 years I was pulled over three times, 2 tickets, one earned, one from an a-hole for nothing. The wife was pulled over thrice, two tickets from to OBVIOUS a-holes. Our son drove to Akron, about an hour and was pulled over three times for a tail light out, a bit aggressive? I won't discuss the other incidents but we never had a problem in PA near that in Ahia.
Ahai has a major county police force that PA didn't seem to employ, they are tax collectors in a real sense. If you drive you pay the ticket tax. They predate during drive time, disappear until the next drive time in general. Then, after about 10:00 p.m. and really after midnight they move to drunk driving mode, if you are driving you must be drunk. My wife was stopped for drunk driving, I was a passenger. She never drinks but didn't dim her light to an oncoming police car, with a police car following her at a distance of about 10 feet for miles. Think she was a bit distracted? at 2:00 a.m. within three miles of our home? A-holes at work trying to bait her into a minor mistake which they did. No ticket this time but they wanted to.
Neighbor kid, was 21, acted like 14 worked part-time as a town cop. The stories he told me were disturbing. The radio system reaches across the entire county and they played a game of seeing which cop could pull over the most red cars in an hour, the most of whatever you can think of in an hour. I can attest he was aggressive. Abusive but it sure did ring up the cash register for the county. The a-hole mentality here is rampant, sadly. It gives the cops a very bad reputation. My wife, a gentle soul, is furious upon seeing a cop and unfortunately, she sees numerous ones on the way to work each morning (drive time) as they attempt to hide in places where those late to work may speed a bit, exit ramps, etc.
I used to respect the police, I no longer do as a whole but very individually. Ahia in general and one horrific incident in PA involving my wife and infant son left by a "cop" in an inoperable car (pre-cell phone days), in January, along an interstate highway because he "had a meeting". No call, no help, nothing. No respect to me, no respect for them. Tax collectors and jerks, sad but true. That is our experience, all true, nothing embellished.
