That makes more sense.
This still just boggles my mind, though. I've been in criminal courthouses in LA, Hollywood, Ft. Worth, Dallas. . .there are usually a ton of cops.
Even in a civil courthouse, there are tons of bailiffs. I'm just thinking about the county courthouse in downtown LA. If you shot someone in a courtroom by the time you got halfway down the hall there'd be bailiffs pouring out of every courtroom.
What they need is in a situation like that for someone to be able to hit an emergency alarm that would seal the exits.
Bad if the emergency is a fire though, or if the shooter is roaming the halls killing indiscriminantly.
