No, for anyone who carries and gave it a thought, it is:
(1) process
(2) duck down and draw
(3) wait for the panicking people to get out of your line of fire
then comes the rest.
Of course it is different in situation when you have your loved ones with you. Then it is.
(1) process
(2) get up in the direction away from your family and in a manner that draws attention of the attacker, all that while drawing
(3) try hitting him while being shot
Reaching for gun and drawing the gun is actually the easiest and fastest part if you train it a bit. The hard part is getting the sights alined effectivly on the target and avoiding panic shots in the general direction of threat, but not exactly into the threat (unless you are lucky).
