Video #1 - Unethical? The guy says pistols are an offensive weapon. If that difference in opinion makes him "unethical," no wonder you were ridiculous enough to post the additional videos as "proof" of officers misconduct.
Video #2 - Canton cop in the worst part of town dealing with a "lawful" CCW holder there with a crack addict and a prostitute in his car. If you're doing with a car load of criminals and felons you need to talk tough. I'm betting you don't work in the ghetto with some of the dirt bags that dwell there on a daily basis, therefore your opinion on the matter is irrelevant. By the way, that badass Canton cop won in court and his getting his job back.
Video #3 - Cop whacks a suspect two to three times on the arms who, among multiple other people, fled from police during late night hours?
Yeah, what a horrible incident.
Video #4 - Cop tosses some drunk broad out of a bar onto her face at 2 am. She wasn't complying with is lawful commands and got tossed. You run the risk of injury if you disobey a lawful command. Get used to it. If you don't like it move somewhere where they allow law violators to walk all over the police.
Video #4 - Some random third world country. Completely irrelevant, what the hell are you trying to say by posting this?
No, not all police officer are angels, but the videos displayed above are a pathetic excuse at proving a point.
