Lots of police air and ground activity around LAX. No cars being allowed to the terminal. Arrivals and departures still operating. Nothing on local news. I'll update if I learn something. EDIT: Terminal 3 being evacuated. EDIT: KCBS reporting gunshots in terminal 3. EDIT: Several news helicopters on the scene, and I think flight operations have halted; haven't seen a plane take off or land in a while. EDIT: Arrivals being allowed to land; all other aircraft being taxied to parking. Looks like a full ground stop. EDIT: Just saw two planes take off from the south departure runway; guess not a full ground stop anymore.
