Around the neighborhood, people thought they saw a gunman wielding an MK-47 and so they dialed 911 and the police showed up to investigate. The gunman was found near Bungie Studios and the cops managed to catch him but to their surprise, the "gunman" was actually a Bungie employee who was actually wielding a replica of a sniper rifle from the Halo games. There were no charges and the police told him and Bungie to transport the gun more discretely in the future.
