I noticed the early and mid nineties saw a lot of violent crews in NY. The common denomonator was:
1) they were all in their early to mid 20’s
2) none were made
3) all were very violent
4) all were involved in high risk crimes such as armed robbery and home invasions
5) all had very short careers
6) most of the crews cooperated
7) all these crews seemed to emerge the day after goodfella’s was released
8) this was clearly a “ new york thing “.
9) philly had a bit of a war but nothing like the wannabe crews in ny.

You had the tanglewood boys, gianinni crew, bath ave crew, 20th ave crew, and a few more. The killings commited by made guys was much more methodical such as lucchese and colombo. Whereas the young wannabe crews were just reckless and violent.
Looks like that era is done.
Did goodfella’s contribute?
