Okay, this is a question that's been on my mind lately.
For big events at work, I'm usually in charge of lights, lighting. During December we usually have about 6 big events (>1,000 people) at night in the Sanctuary. Last night I ran lights, and sound, for a choral concert with about 1,700 in the house.
So in case of an active shooter, assuming I have enough wits about me to think of this, what do I do with with lights? I'll give my thoughts
All on, bright, so that people can see to get away and so I security can get a clear sight picture?
OR
All off, so that it's harder for the shooter to see? And conceivably so people could stand a chance at rushing the shooter.
