|Down at the bottom of the list may be found the following suggestion:
"As a last resort, working together or alone, act with aggression, use improvised weapons and fight."
Now the shooter certainly didn't limit himself to only improvised weapons when he initiated his shooting mayhem. Why hamper oneself with the improvised weapons when he can arm himself with actual weapons, designed for fighting?
Also, why is standing and fighting the suggestion of last resort when it would seem that immediate resistance, using weapons by design and mounted early in the event, would be more disruptive to the shooter's intent?
