Police found a frightening collection of assault rifles, bomb-making instructions, drugs, at least $40,000 in cash, and Nazi paraphernalia in the Long Island home of Edward and Sean Perkowski early Thursday, as the New York Times reports.Authorities raided the 20-something brothers' Mount Sinai home and found swastika flags, at least one photo of Adolf Hitler, six assault rifles, a handgun, a shotgun, four rifles, a stun gun, and a black binder apparently containing handwritten instructions on how to craft explosives. Cops also found shrooms and marijuana, and arrested Edward, 29, on weapons and drugs charges, and Sean, 25, on an outstanding bench warrant."We neutralized a clear public threat," the Suffolk County police commissioner, Timothy Sini, said in a press conference, likening the potential threat the Perkowski brothers posed to that preceding the tragic Orlando mass shooting last Sunday.Edward Perkowski's lawyer told a local CBS affiliate his client plans to fight the charges "one hundred percent." According to one friend, the man ran a military surplus business—which could explain the guns, but doesn't quite account for all the Nazi shit. But a neighbor, Brian Saltzer, complained of ongoing problems at the house, indicating he's called the cops multiple times to alert them of possible drug dealing and violence.Photo via the Suffolk County Police DepartmentRead: Someone Bought a Hitler Statue for $17.2 Million at a New York Auction
