Police prepare for potential school violence
Mock school shooting exercise
Yellow police tape cordoned off the entrance to Baldwin High School on Thursday, and a throng of officers loitered nervously outside.
Gunfire popped inside the building. An armed suspect had started shooting in a second floor classroom. Radios crackled. Someone was down in the stairwell, shot in the shoulder.
A phalanx of five officers charged up the stairs, guns drawn. Down! Get down!
