They shot out the windows in the direction of the police. Officers returned fire, and the gunmen retreated from the windows; no one was injured. Klebold then removed his trench coat. He shouted: "Everyone with a white cap, stand up!" When no one stood up in response, he said, "Fine, I'll just start shooting!" (Il nastro del tempo)
