Why do Policemen have such god complexes?

I made one mistake while driving and this Complete Jerk of a cop would/could not give me a break. I was completely polite and curteous, I pulled well off to the side, Put on my flashers,Turned the car off and had my keys up on the dash and turned on the overhaed light. When he walked up behind me I had drivers license and registration ready for him with my hands on the wheel so he could see them clearly. I Want any officer to know beyond any shadow of a doubt that I am not a danger to him or anyone else. I explained exactly what happened and it really was a one time mistake I really had a bone head moment there. And the SOB gave me a $150.00 ticket and treated me like I was a Convicted Criminal!!!! What a complete ass! That really changed my attitude about cops! WTF you bastards! How about a cutting us a freakin break! Most of have to WORK very hard for our money! And can’t afford to be Ripped off like that! $150.00!!!! Thats a shithole pumping if I ever heard of one!
