Sometimes the status quo is both unbearable and self-supporting. If it won’t allow for reform, then sometimes the only recourse is to sweep it aside and replace it with something that isn’t a source of despair and horror for most people.
A riot is the language of the unheard. If it won’t hear, it must be made to hear.
Or do I need to use shorter words to explain it?
In a perfect world, you are right. In other countries, police reform from outside has been attempted and implemented and has sometimes even worked. It’s hard, it’s unceasing effort to maintain, but it’s worth it and it’s necessary.
In the US, it’s occasionally been tried, in local areas, in cities, in states, but for whatever reason (*cough*police unions and Law’n’Order conservatives*cough*) have mostly failed. The system is big enough, and flexible enough, and powerful enough, and flat out corrupt enough, to resist external pressure. The US police force system as a system (being a system of interlocking, reinforcing, semi-independent forces, each looking out for the others at the expense of “civilians”, as they universally call everyone else) must be destroyed utterly and replaced with a modern civilised well trained police force system. One which is actually there to look out for the well-being of everyone, not a barely-disguised protection racket.
Your police system is poisoned from its birth, and you deserve better, and you’re not going to get better from it incrementally or by asking it nicely.
And when you’ve fixed that, the rest of the world recommends you work on your Health system, and have a good long hard look at the concept of “elected judges”.
