I have stopped about 20 people in the past month for various traffic violations....of those I can think of two that were polite to me. Most were complete a$$holes. As if it's my fault they blew the red light or were flying through the school zone.
So because 90% of the people I stopped were frickin jerks, should I let that effect my attitude towards everyone?
Believe it or not, I always start off on the polite foot when stopping someone.
First of all, you never know who your stopping and second, it's always easier starting off nice, you can always move up to being a prick if someone starts with you, it's very hard to go the other way.
Don't judge what we do till you've been there and you know how hard it is.
Oh, and adowell, most departments have a policy on civilian ride alongs. I would call your local agency and ask them when their shifts start, show up at the station and speak to the shift supervisor. They will always let you ride. It might give you a different angle on this, plus it should be a lot of fun. Suggestion, ride on the afternoon shift, usually from around 3:00pm to 11:00pm, you'll see the most action.
