Ghost, I am so so sorry that something so awful had to happen to you, I could not even begin to imagine what you are going through, but I can guess you have been replaying the entire event in your brain more times than you would want to. Being wronged is almost crippling to a person, and of all people in this world, you did not deserve to be wronged by anybody, Ghost.

All I can say is in time the anger and frustration of being treated so unfairly will eventually subside, and this will be a story you will find humorous than one that makes your blood boil when thinking about it like Im sure is the case for you right now. It sure would be for me.

I had a confrontation with a cop several months ago, I was driving home and it was late and I hit a major traffic jam on the highway to my house. When I finally crawled up to less than a block away from the turn to my neighborhood I couldnt see the intersection I needed to turn at cuz the cars were so backed up but when I finally got up to the left-turn lane (still unable to see intersection because the lane starts really far back) I got in and at that point saw that the intersection and the turn to my neighborhood was closed off. Complete mistake on my part, however the lane was not blocked off, there was no sign or warning not to get into the lane to my knowledge. I know I didnt hit any cones or remove any tape. Well anyway, the cop directing the traffic at the intersection stormed over to me burning mad, yelled at me, told me how inconsiderate I was of the other drivers for trying to turn at this closed off intersection while they are sitting in traffic, and with such hostility was like "what were you thinking??? did you really think you'd be able to turn here, HUH???" I so badly wanted to defend myself because it absolutely wasn't my intention to try and pull a fast one in this traffic jam like he was making it out to be, I just honestly didnt know that it was closed off, and there was no warning. With everything in me I said simply "Im sorry officer, what should I do now?" He rolled his eyes and said "you can sit there until I wave you through, but expect to wait a while." Then he stormed off to his buddies while pointing to me and huffing and puffing over what a stupefying idiot I am.
After about 10 minutes of my watching him blow his whistle at other cars and yell and have attitudes with them (though not quite like what he had done to me) he waved me through, and as I slowly drove by him he yelled "next time I'll give you ticket for pulling that kind of stunt!!!" At that point I so wanted to put this asshole and his rediculous ego/power trip in his fucking place...but I bit my tongue...HARD. It made me so angry because he was treating me as though I had some ill intention, and that he so eagerly assumed the worst about me. I didnt understand what exactly he was trying to accomplish talking to me the way he was since there was nothing I could do to change it.
I knew I shouldn't argue with him or defend myself or attempt to explain because he was intoxicated off the fumes of his ego. My trying to do any of those things, which would be a reasonable reaction by any normal persons standards, would have given him reason to do to me what he really would have liked to have done. If I could give him more reason to be irate, he would have taken me up on it, and punished me because he could, and I asked for it in his eyes.

It hurt my pride to just take it, sure. It really hurt my pride. But I had to look at the end result, and I knew I wanted to go home that night after all that time sitting in traffic. Arguing with an emotionally unstable police officer over something that couldn't be changed would probably not have the end result I wanted. I took comfort in that, even though I was wronged, I had to size up my opponent before a potential match, and I feel as though I made a smart move letting him have his little trip on me, as humiliating as it was for me to do so. I would never have won or been able to right the wrong.

With your situation you really did do nothing wrong and an officer of the law told an innocent civilian onlooker to fuck off. Your reaction to his audacity is completely, 100% understandable. I dont want to say you should be proud, but you should consider yourself fortunate (for the most part) that you got a first-hand insight into the true colors of some policemen and what they are capable of when they have a little power. An experience like yours will make you all the more empathetic to stories similar, you will always be able to relate your story to others, and never will you be blase on the subject of law enforcement and their power over the people. Not that you were before, but now you most likely never ever will. Like the old saying goes, "what doesnt kill us..."

Anyway, again, so sorry, Ghost. Keep your mind occupied and take care of yourself so this unfortunate experience doesn't consume you more than it already may be. *hugs*
