The sad,sad truth is that most of the cops these days are idiots,and that might even be bragging on them.
I went through a similar,but MUCH less threatening thing a few months ago. Had a highway patrolman heading towards me as I entered a 45 MPH speed zone and slowing down,do a sudden U-Turn and put on his flashers. I figured he got an emergency call and was heading that way,so I paid no attention to it. Then,suddenly,he was right up on my rear bumper.
This was in a 4 lane with no where to pull out of the traffic lane except for people's driveways,so I decided to drive on for maybe another 50 yards to pull off into a shopping center parking lot where we would both be safe from traffic.
He was SERIOUSLY pissed when he ran up to my car window. I would see a vein throbbing in his forehead,so naturally,I asked him "Why are you stopping me?" He said I was going 66 in a 45. I looked at my speedo when he pulled in behind me,and I was running 62 MPH in a 50 MPH zone,but had just started slowing down.
I thought the stupid SOB was going to try to drag me out of the truck.
And this was maybe 2 PM on a weekday afternoon,with sun in the sky and light traffic.
Then he started screaming at me for not immediately stopping when he pulled in behind me. I told him I didn't want to stop in a traffic lane on a 4 lane highway when there was a whole freaking shopping center parking lot to pull off in just up the road,and since I hadn't tried to speed up to avoid him,I figured he would be smart enough to figure that out.
That seemed to make the little freak even madder. Someone had questioned his "Author-a-tay".
First speeding ticket for me in over 30 years.
Now *I* have an attitude,and if he stops me again it could get ugly.
