Many countries just hide poverty and homelessness. For instance by sending them all to a district foreigners don’t go to or know about.
In NYC and a lot of US cities, things can vary from block to block. You could live in Manhattan in a $3M apartment and the nearest grocery is the same one that NYCHA residents use. I'm not saying being poor makes you do crime, but if you are someone who is in a gang and doing crime, you are more likely to live in NYCHA than in the $3M apartment.
It's pretty normal in neighborhoods like UWS, Chelsea, LES/East Village, North Brooklyn to have block to block variance like this.
My subway stop has had 2 drug/gang related murders in the last 2 years, and it's also the first stop into Brooklyn from Manhattan. You'd not expect that.
So yeah, I think we also hide the problem less in our cities than Europe.
Is that a lot, or not a lot, to expect [EU perspective. I'd....expect....fewer than 2 in 2?
There are 472 subway stations in NYC, and generally less than 400 murders city-wide per year.
Generally murders happen a lot of places other than just subway stations, so having a murder at my subway station 2 years in a row is.. surprising.
