On Staten Island a young man was allegedly caught with homemade bombs under his winter coat, and officials want him and all the other bomb hobbyists out there to know that's not OK. "I made it," John McCloskey told cops, according to the Staten Island Advance. "I'll show it to you. I'm going to prank my friend with it." The 19-year-old allegedly claimed that video tutorials showed him how to make a bomb out of wire, nails, metal and gunpowder. At his arraignment today, McCloskey will be charged with first-degree criminal possession. “Although this defendant claims that the [device] he manufactured was intended as a prank and not to be used, this was clearly a dangerous situation with the capacity to injure many people,” said DA Daniel Donovan in a press release. “There is nothing humorous about attempting to manufacture a bomb."
