I imagined the scenario of an armed gunman, possibly with an AR style weapon busting in the back and start trecking towards the front of the auditorium (possibly towards an intended target). I sit on the end of a pew and would have perfect chance to pull my weapon and shoot the gunman in the back as he walked up.
I came to a crossroads at this point wondering what I would need to do in such a situation. No shots were fired as of yet, but the only conclusion one could make is the gunman was going to kill someone.
What would you do in this situation?
