The post is a huge list of links of police brutality on innocent protestors, bystanders, and media well within their rights. This post has nothing to do with how the police treat "gangsters", unless you mean something different by that word.
Defunding police because of police brutality is swallowing a spider to catch the fly. You do NOT want to live in a place without police. I think it would be much more productive and realistic to have a really deep study of how policing in America is different from other countries, and what can be done to normalise it. America is pretty gun crazy, and that doesn't make a cop's life any easier. The flip side of that is…
False dichotomy.
You can defund the police, by not sending armed, militarized police to do the bullshit parts of their jobs, while still responding to violent incidents.
For 99% of police calls, you don't need an armed gunman to show up. Of the 1% that you currently do, more often than not, that armed officer won't even show up in time.
