An anonymous reader writes: U.S. Park Police reported hearing gunshots fired near the NSA headquarters on Tuesday. Hours after gunfire ringing, the FBI said a suspect has been arrested for a series of shootings in the Washington-Baltimore area. The agency believes the suspect is responsible for several shootings, including one on the Intercounty Connector in Maryland and one at Fort Meade, Maryland — where the NSA is located. No one was injured, but NSA found damage to a building near the highway that passes by its campus, a federal law enforcement official said. Investigators are looking into the other shootings that have happened in the past couple of weeks to see if there is a connection. Those shootings happened outside a mall, a theater and a Walmart. Someone also shot a landscaping truck.
