Sen. Chuck Schumer on Sunday proposed new legislation to require the FBI to sign off on body armor sales to civilians.

The announcement comes one week after mass killer Connor Betts — clad in body armor — opened fire in a trendy Dayton, Ohio, neighborhood and killed nine people before he was gunned down by police.

Schumer said anyone can now buy a bulletproof vest for $185 and a tactical mask for $10 under current law, Schumer said at a press conference at his Midtown office.

“With the click of a mouse, scroll of a thumb, dialing of a phone, someone up to no good can get this,” he said. “What we have learned is that a good number of those intent on mass shootings buy body armor,” the Senate minority leader said. “They want to kill as many people as possible.”

The restrictions would not apply to law enforcement personnel.
