I'm not sure I get it. Why would you do that?
I know that there are ideologies that bring people to hate police, but I can't imagine the inhabitants of housing projects to be fans of such. So why would you lure cops in and try to assault them?
I'm not a big fan of law enforcement myself, but I am not sure I would have even THOUGHT of this.
And attacking EMTs and firefighters? That's just the lowest grade of scumbaggery.
I acknowledge that I am generalizing, but I used to work for a large municipal public housing authority, so I am basing this on my personal experience with the overwhelming majority of our residents. I've been "out" for more than 20 years, and I'm sure things have gotten worse since then rather than better.
Micro, you have to recognize that here in the U.S., it is the dregs of society who live in public housing. Collectively, they have no respect for authority. They are only interested in what "the man" can and will do for them. There is no sense of personal responsibility. There is no morality. Collectively, the people in public housing are not immoral, they are amoral. Human life has no value to them. There is no discipline of children, so they raise up undisciplined adults ... most of whom are functionally (if not literally) illiterate.
To such "people" (I use the term loosely, since many of them are closer to animals than to people), shooting fireworks at police and firefighters is just another way to have fun. "The lowest form of scumbaggery"? What else would you expect from the lowest form of scumbag?
We had a sitework contractor doing projects for the authority who was widely believed to have
serious Mafia connections. It was known that most of his workers were ex-cons, and a professional cage fighter would think thrice about taking on some of these guys. THEY would not work in our projects past the time when school let out, and they would not send in a crew of fewer than three man to do even the smallest task. Why three? One to handle the rake, one to watch the back of the guy handling the rake, and the third to guard the truck ... with a shotgun. Remember, this was more than 20 years ago.
When I started the job, the director of the agency personally escorted me to each project and introduced me to the key residents in each location. The reason was so that the residents would know I was one of the people who was off-limits to being mugged in the project. But ... he cautioned me to never EVER go to any of the projects after dark.
