Troll aside i think everyone has different sides because no matter what there's always going to be someone doing a job that they really shouldn't be doing and someone is going to run into these people eventually. I've had good experiences and bad experiences.
When i had the STi i got 4 warnings when i had my old beaters i got 5 speeding tickets, maybe that had something to do with it and maybe it didn't but MOST cops i know are out to do their jobs and all they want is a little respect when they stop you.
