I have the utmost respect for police officers who morally and professionally fulfill their duties.
I think it's appropriate to share a shortened version of one of my teenager-in-highschool nights here...
Me and my buddy were at a party (neither of us were intoxicated) and we had to go get some ice from the gas station. So we hopped in the car and headed out; I rode shotgun. My buddy turned his lights on AS he pulled out of the driveway so he was technically on the road at the time and he technically broke the law. A cop followed us to the gas station, and we pulled in there and he pulled next to us but didn't get out so we were like, okayyyy haha
Anyways we were counting quarters so we could get a few dollars and buy a bag of ice right and the cop jumps out of his car and he's like WHATS IN YOUR HANDS WHATS IN YOUR HANDS to me, so I was scared to death and I dropped the quarters on the floor of the car at my feet. He was thinking I was rolling a joint or soemthing; I said it was just change lol and he was shining his light all over...he said he smelled marijuana on us so we had to get out to be searched and all that good stuff. Keep in mind, we just came from a party...
Anywho, we were getting frisked and he reached his hands in my pants to check around the groin area and I jumped back and was like

man (naturally you know? I couldn't really help it I didn't expect it) but he slammed me against his car and cussed at me about resisting blah blah blah I was just thinking to myself whatever...I wasn't about to mouth off to a cop, you never win in that situation.
So the same happened to my buddy right after that, as the officer's partner frisked him. They pushed him against the car and he pushed back; I told him to sit still but he was so stubborn he didn't stop
Him being on the wrestling team in HS (those were the days haha) he sprawled when they tried to take him down, and I was just watching as all hell broke loose from there...once they got on him they put cuffs on him and a backup car arrived then, the guy gets out and asked what happened and my friend is now sitting on the parking lot ground with cuffs on and another cop standing next to him. He was calm and quiet, and he realized he was being unbelievably stupid by resisting like that. This cop that just got here actually looked at him after he talked to the cop and then walked over and kicked him to make him lay down, then he got on him and put his knee on his back and grabbed him by the hair pulling his head up and asked if it felt good, while he pushed all of his weight onto that knee.
At this point, I was like WHAT THE f*** MAN!?!?!? There was no reason for that, and my buddy was just yelling/screaming cuz it hurt so bad. I was furious, but what could I do? I had another cop standing next to me, and I wasn't about to go to jail too. The cop that was already beating up on him then pushed his face onto the ground pretty forcefully and cut his forehead open a little bit. My buddy started calling him a pig and the cop hit him a couple times, and he picked him up by the arm like they do and walked toward his cruiser. When they got to the hood, the cop swung him by one of his arms and slammed him into the hood. Then he grabbed him and slammed him into the trunk, then he opened the back door and threw him in.
I felt horrible, useless. Anyways, that night was pretty bad, I went to pick him up at the jailhouse and got home around 6am. He was all bruised up and cuts were on his head and face and knees. He went to the doctor, had it all documented and took pictures. We got to court a few months later and the lawyer tried to get him out of his charges from the state, but he knew if he wanted to sue them for brutality he would have to hire another lawyer and open a new case and crap and he decided it wasn't worth it.
At that court session though, the police handed over the tape of that night, and the judge showed it before they called me to the witness stand. I couldn't believe my eyes...the tape was rewinded and recorded over. Everything that happened after he was arrested and settled down was completely erased and it went from that point to the next traffic stop the officer did the next day. That was all of the "police brutality" evidence we had anyways, and it was now gone.
Anyways the police officer who took my friend to jail (the cop that beat him up) was called to the stand to tell exactly what happened from the moment he got there until he left. He said he got there and they needed help transporting my friend so they asked him to drive my friend to jail. Then he said he walked the suspect to the car and left, following the orders he was given. He forgot to mention the part where he beat him, the part they re-recorded over on the tape.
Oh well. What can ya do. We were both young and dumb, he was just dumber for thinking he can play games with the cops. That doesn't make it right what they did though.
