Cops - They Do Some Weird Stuff And Sometimes Tick Me Right Off

So yesterday (Thursday) evening I was driving back from Salt Lake at about midnight. Now yes midnight is fairly late but not unusual, there was still a crap load of traffic on the I-15. What gets me is why did 3 police cars in total feel the need to tailgate and follow me?

The first one did this just as I got on the freeway at 600 N. He followed me closely for about 20 seconds, then pulled along side for about 10 seconds and then sped off to the next car in front and did the same. This exact same thing then happened at about 3300 S, I think with exactly the same cop. Then it happened again at about 9000 S, this time with a different cop. And then another on Redwood Road between Bluffdale and Saratoga Springs. This one tailgated me the whole way.

Now I understand they may have been looking for someone but why would they check every car rather than specific models? Why did he pull along side, yet not far enough forward to see me, and he wasn't checking my speed, all 3 had their radars on (thank you radar detector).

Why could they not be doing other more productive stuff? Why do they feel they can do what they want, like go from the outside lane to the inside lane at probably about 85-90 mph without using indicators? I mean that 4 lanes!

I remember about 18 months ago in Lehi I came to a 4 way stop. I stopped and a car approached from the right, I kept an eye on it because of crappy Utah drivers (see earlier post) and as I was about 1/4 way across noticed he was not going the 25 mph limit, more like 35, and that it was a cop, with no lights on or siren and that there was no way he was going to stop. I slammed on my brakes and luckily he did too. My guess is he heard that Krispy Kreme had the hot doughnuts ready. Do cops not have to stick to the limit or stop signs? He should write himself a bloody ticket. They seem to like writing them for me and everyone else.

I don't mind cops, but they do the strangest things sometimes and if they want to hold everyone to the law, they better keep it too unless they have a reason, especially when doing something as dangerous as tailgating for a few miles, that is just not needed.
