A police officer attempts to stop a car for speeding and the guy gradually increases his speed until he's topping 100 mph. He eventually realizes he can't escape and finally pulls over.
The cop approaches the car and says, "It's been a long day and my tour is almost over, so if you can give me a good excuse for your behavior, I'll let you go."
The guy thinks for a few seconds and then says, "My wife ran away with a cop about a week ago. I thought you might be that officer trying to give her back!"

A male driver is pulled over by a cop and the following conversation takes place:
Man: What's the problem officer?
Cop: You were going at least 75 in a 55 zone.
Man: No sir, I was going 65.
Wife: Oh Harry. You were going 80.
(Man gives his wife a dirty look.)
Cop: I'm also going to give you a ticket for your broken tail light.
Man: Broken tail light? I didn't know about a broken tail light!
Wife: Oh Harry, you've known about that tail light for weeks.
(Man gives his wife a dirty look.)
Cop: I'm also going to give you a citation for not wearing your seat belt.
Man: Oh, I just took it off when you were walking up to the car.
Wife: Oh Harry, you never wear your seat belt.
Man: Shut your mouth, woman!
Cop: Ma'am, does your husband always talk to you this way?
Wife: No, only when he's drunk.

Unless the police are using laser guns to check the speed of a approaching vehicle,  according to FCC regulations concerning the use of radar guns the police car must be visible from either side for a minimum of 1/2 mile.  I have received a speeding ticket and the cop car was visible for less than 300 feet.  When i got to court, I pleaded innocent so the cop had to appear.  When the court date arrived, I showed up to the court with a copy of FCC regulations for radar gun usage.  The judge was a bit pissed off at the cop, when i showed photos of where his car was located and the lack of required visible distance.  She dismissed the case and I walked away.  I also informed the officer, I know what I am talking about when it comes to radar usage and FCC regulations.  I have a degree as an Electronics Engineer and also served in the USAF repairing RADAR systems on jets.
Also according to FCC regulations speed traps like some of those in any state is a violation of FCC Regulations and the possibility of losing RADAR gun usage.

Now if they only come up with an illegal alien trap and fine them money . We would be out of debt in no time .

Many states set this up just for revenue. Brother in law was a trooper. He had a quota to meet writing tickets. Writing out of state tickets was the best for them. Most people, 99% wouldn't come back to contest it. The plan was to make ten times the price of the cop car and his wages.  Good deal for the state huh ? Just extortion by police forces. 

Did you notice that the yellow light is much shorter where ever  the red light camera's have been installed?  Yes folks, its all about the money!
