The Senate’s top Democrat, Chuck Schumer, said Sunday he would introduce legislation after the summer break that would require the FBI to regulate the sale of body armor. The call came after a mass shooting last weekend in Dayton, Ohio, during which a man wearing body armor killed nine people. Schumer said he wants the FBI to set standards for eligibility of purchase of bulletproof clothing and other body armor, according to the Associated Press. The bill would provide exceptions for law enforcement and other safety and security officials.
