Its not a claim, its a statement of fact. On any given day, I could go walking down the road carrying bats, golf clubs etc, and never even be approached by police. Mind you, I live in a free country, with free speech, where the cops aren't out to put everyone they see on the wrong side of the law.
If, if if.

... You're making stuff up again, creating a strawman scenario and arguing for it. The incident in question (man carrying baseball bat and arrogant, ◊◊◊◊ of a cop attacking him) did not take place
"in an area, where gang violence was rampant and there had been ongoing trouble". Please stick to what actually happened, a cop came up behind a man innocently carrying a bat in a pedestrian area where the was no trouble and nothing untoward going on, grabbed him without warning and assaulted him.
Its obvious from your comments that you're an ex-cop, and you want to take this cop's side, but please stop making up fanciful scenarios to argue against, none of which bare any relation whatsoever to what actually happened. Argue THIS scenario without adding or altering things from your imagination.
What I find most disturbing about this incident is the statements made by police that man refused to engage when the officer tried to talk to him, leading to him being detained and arrested. As a general member of the public, you have no legal obligation to answer general questions or engage in a conversation with a police officer. Under the right to remain silent, you can decline to answer questions or walk away, provided you are not detained, under arrest, or operating a motor vehicle.
