Situation #1
I got pulled over by a State Police who clocked me at 10 over on my motorcycle. By the time he turned around and pulled up behind me, I was off the motorcycle, helmet off, hands in sight, and the motorcycle shut down. He was very polite and asked why I was going so fast. I didn't have a good excuse so I didn't bother.
He let me off with a warning, and was very polite.
Situation #2
I got pulled over for 10 over in my truck by a small-town cop at about 1:00 AM. I had to drive for a little while before he pulled me over because there was no safe place to stop. I tapped my brakes and continued on at a slower pace. Eventually I stopped just inside of the city limit sign. He warned me about deer on the road and let me go. He was very polite.
Situation #3
I got pulled over for running a "stale yellow" (I didn't clear the intersection before it turned red.) I got pulled over. I thought I had cleared. I apologized. He let me go with a warning. He was very polite.
Situation #4
I got pulled over for 11 over in California. He gave me a ticket. He was very polite.
Situation #5
While at a local dance hall for my sister's 30th birthday, I had one drink early in the night, and then stayed with the party until 2:00 AM. While in there someone (I think it may have been my sister's ex-boyfriend) covered my license plate light with shoe polish, so it looked burned out. A policeman saw me leave the bar, and followed me. When he saw my light "out" he pulled me over. He asked how many drinks I had, and I told him "one, several hours ago." He suggested that I fix my light as soon as possible. He was very polite.
Shall I go on? I think is the only way to re-build respect for Police. But nobody's going to read a thread called "A policeman was polite to me today." Let alone run a news story on it.
