He has no venue to respond. No one even accused him of being racist, besides you. How is he supposed to defend himself, come onto hacker news and write a reply?
The police dept released a statement said they'd review the video and take any action deemed necessary. What you would have them do?
That, but with an independent third party instead of the police dept. Police are clearly not capable of policing themselves.
Stop murdering or otherwise harassing black people...?
Stop switching cameras off, stop blocking any attempt at creating accountability, stop working for the police.
Quick question. How many black people did US police murder last year? Order of magnitude. How many would be few enough for you to say that the police have "stopped" - 100? 10? 1? 0?
My guess is that the actual number is a lot lower than you're thinking, even when counting unintentional things like "police officer made a mistake, shot innocent person" and "pig strangled someone a little too long". Not to say that that's excusable when it does occur, but...
The thing that goes after the but is called an "excuse".
