Red light
 

A police motorcycle officer stops a driver for shooting through a red light.
The driver is obviously born out of wedlock, steps out of his car and comes striding toward the officer, demanding to know why he is being harassed by the Gestapo!
So the officer calmly tells him of the red light offence. The motorist instantly goes on a tirade, questioning the officer's ancestry, sexual orientation, etc., in rather explicit offensive terms.
The tirade goes on without the officer saying anything.
When the officer finishes writing the ticket he puts an "AH" in the lower right corner of the narrative portion of the ticket. He then hands it to The 'offender' for his signature. The bloke signs the ticket angrily, and when presented with his copy points to the "AH" and demands to know what it stands for.
The officer says, "That's so when we go to court, I'll remember that you're an a*sehole!"
Two months later they're in court. The 'offender' has a bad driving record with a high number of points and is in danger of losing his licence, so he hired a lawyer to represent him.
On the stand the officer testifies to seeing the man run through the red light.
Under cross examination the defence lawyer asks; "Officer is this a reasonable facsimile of the ticket that you issued to my client?"
Officer responds, "Yes, sir, that is the defendant's copy, his signature and mine, same number at the top."
Lawyer: "Officer, is there any particular marking or notation on this ticket you don't normally make?"
"Yes, sir, in the lower right corner of the narrative there is an "AH," underlined."
"What does the "AH" stand for, officer?"
"Aggressive and hostile, Sir."
"Aggressive and hostile?"
"Yes, Sir.
"Officer, are you sure it doesn't stand for a*sehole?"
Well, sir, you know your client better than I do.
