> they'd most likely arrive shooting, as they do when there are parties in slums.

Can you please link to the news articles about these slum parties that are broken up by officers who start shooting the moment they arrive? Seems like something that would definitely get reported on.

In all my time living in low-income housing, I never witnessed something like this. And I had plenty of sleepless nights when neighbors would throw ragers. Some got broken up (mostly when a fight would break out among attendees), and I'm sure some of the cops weren't pleasant. But I never witnessed cops jumping out of their cars with their guns blazing.

Although I'm one piece of anecdotal evidence, so I'd like to see the evidence you have of this event.
