Recently released footage from a Muni security camera allegedly shows that on Sept. 23, Nikhom Thephakayson pulled out a .45-caliber pistol, raised it, pointed it across the aisle, put it down and continued to pull it out multiple times, even wiping his nose with the handgun. Absorbed in their phones, not one of the dozens of passengers reacted until he fired a bullet into the back of Justin Valdez, 20, a sophomore at San Francisco State University.
