I think the big change bro, is the amount of gang activity in Brooklyn now.
Gangs didn't get really big in NYC (Bloods and Crips, specifically I'm talking about) until 1997-1998. They were there before, but it was mostly prison. Now, in 2020, most all these kids are in gangs or affiliated. Plus the rapper scene is really just gangland now. It's not really people during it for the art. And add on social media, where there's more public displays of disrespect, which leads to need for people to retaliate/to not look weak on social media.
Back in the early to mid 90s, it was much more dangerous to go to hoods you not from (Brownsville, The Stuy, Flatbush), because your likely to be confronted/robbed/jumped. It was damn near almost a guarantee. To me, back then, it was more of a poverty thing. nikkas was really broke. shyt, I remember me and my nikkas outside of that McDonalds by Brooklyn College, running nikkas pockets, just because we was broke.
Nowadays, nikkas doing crimes/shooting are nikkas that got on thousand Balenciagas and Amiris.
That mcdonalds was infamous for shyt..esp on half days.
