Saw a great (and scary) video on RUN, HIDE, FIGHT (from http://www.readyhoustontx.gov) -- link to video is here.
Other take-a-ways:
- Always have a plan A, B, and C.
- If you can't run or hide, fight with everything at your disposal--engage and neutralize the shooter!
- Survive, you're not done until your done!
Please G-d, we should never have to deal with the horror of this, but it's good to learn to be always ready. ;-)
