It's sort of funny how you get used to things and normalize them, especially the violence that occurs in the US. I lived in Chicago for nearly a decade, much of it on the near west side, and it was normal to hear gunshots a few blocks away. Violent crime was normal - a pub restaurant I used to take my kids to along with other families, had a brutal murder where someone got their throat slit. And I wasn't living in a "bad" area either, it was filled with affluent middle class families. This was also with two coal fired power plants puffing away right in the middle of the city (this was in the 2000s even, what a joke!). Everyone just accepted these things as normal for living in Chicago. The US can be weirdly dissonant place at times.
