Rep. Xavier Becerra, a California Democrat, had the perfect excuse for "accidentally" whacking reporters: He called a press briefing to stage a shooting to demonstrate new bullet-stamping technology. But instead of holding it in a committee room, he chose the U.S. Capitol Police range in the Rayburn House Office Building. "We just had to do it at the firing range," he says. "I don't think the chairmen of the hearings would be pleased we were firing a weapon in their room." Or reporters and staff: "It's hard to do a press conference if you're going to take a chance the bullet will hit a person."
