Do you know how many people in the Bay Area stopped reporting crime because the police won't do anything about it?
Get your car robbed? Call the police and they tell you to fill a report out online.
You have a reason to think unreported crime is higher in S.F. than other places? Which is what would make comparative crime statistics inaccurate for S.F.? An evidence-based reason?
Anyone being harmed by violence is too many people, anywhere. I'm sorry if you have been harmed by violence in SF. But in America, it's the safety and comfort of those who are already most safe and comfortable that are prioritized, and the most safe and comfortable believe this is their right. In America, we can't distinguish discomfort from threats to safety.
S.F. is in fact much safer than many many American cities. Deal with it. (And the wealthy are in fact safer than the poor in almost any city).
You want to see a police force that really can't be trusted to do anything about anything, and is engaged in rampant criminality on top of that, plus routine violations of the constitution, come visit Baltimore. Not saying the SF police are "good", I don't think any police are, but you don't have it especially bad in SF. Maybe you don't call the police because you don't think it will accomplish anything -- do you know how many people in the USA don't call the police because they think the police may further victimize them? Probably some in S.F. too, depending on who they are...
I guess you do, so how many?
