A parallel question would be, "What is the crime rate in Manhattan buildings with doorman vs. buildings without doorman."; but for some reason, those who write articles blasting gated communities as asocial do not want to consider that question. Yet, anyone in NY able to afford a place with a doorman ensures their new home/building has one!
Gated communities reduce the 'scouting' and opportunistic crime, but if someone is intent on breaking into your house, neither gates, security systems, or deadbolts will prevent the most capable crooks.
I prefer doorman and gated communities to keep out opportunists and petty thieves, not to mention the rabble that litters, drives across peoples lawn, smashes mailboxes at night, etc.
