As far as him having checked for flights before launching: What a lame joke! I have flown in a full scale helicopter in that airspace, around the Statute of Liberty, etc.. The pilots are in constant communication and visually scan the airspace for potential danger. They can't and don't do whatever the heck they want.
I am one of those people who doesn't need a law to understand that something should not be done just 'cause you can. It is dumb, stupid, moronic and dangerous to fly an RC plane over, around, close to people, buildings, bridges and small farm animals. You could kill people. No law needed in order to understand the reasons this is so. But they are there for those who lack common sense.
This guy is a moron. Certifiable. Sorry, no other way to put it.
