(NEWSER) – It's the kind of luck people only have in the movies. Just how did 16-year-old Justin Casquejo get past the NYPD, the Port Authority Police Department, and two private security companies to reach the top of 1 World Trade Center, the tallest building in the US, on Sunday? It was easy. A "WTC buff," according to the New York Post, Justin allegedly sneaked out of his New Jersey home around 4am and made his way to Ground Zero, where a crack in a barbed-wire fence proved large enough for the skinny teen to fit through. "I walked around the construction site and figured out how to access the Freedom Tower rooftop," Justin said, according to court papers. The rest was, apparently, a piece of cake.
