I grew up in New York City. There are just as many "mad scientist" teen age boys per capita as anywhere else.
Not just teens. Ever hear of NYC's "Mad Bomber?"

I remember as a kid, when you went to the movies, they would put prizes under the seats. Before the movie began, the manager would ask everyone to look under their seats for prizes (like a single serving box of Cheerios).

The mad bomber was acting out of malice, teen boys can be irresponsible and reckless.
