DeBlasio - need I say more?
This isn’t in NYC; these killings are happening in what had been expensive neighborhoods on Long Island (now being re-filled with trafficked foreigners as Americans flee the high costs/taxes and bad Northeast economy). Years ago well-off people lived here and commuted to NYC (and some still do); like NJ, it is simply too damned expensive for most younger Americans (except government employees), so the government is importing foreigners to keep the housing and classrooms full.
