The Denver Police Department is stocking up on pepper spray guns ahead of the Democratic National Convention. The city has ordered eighty-eight projectile launchers that fire plastic balls filled with cayenne pepper and other substances. Denver is purchasing the weapon from SWAT, Security with Advanced Technology. The news comes just weeks after SWAT announced plans to merge with the company PepperBall Technologies. Meanwhile, some residents of Denver are questioning why a half-dozen military helicopters flew over parts of the city on Monday as part of a secret security drill. The Denver Post reported the military aircraft buzzed above the Pepsi Center, the site of the Democratic Convention. A military spokesperson denied the drill was connected to the convention. Lt. Nathan Potter said, “It’s routine preparation for the global war on terrorism.”
