Sorry my friend, that comment has nothing to do with MY postion, that's just a bit of reality relayed as to what actually happened. If I were wrong, the news would have been different.
Just sayin, can you get prepared behind a keyboard? You learned what you know from real world experience yes?
A combination of experience and training, yes. However, they're perishable skills that need to be exercised.
As for the other part, I will never be a victim so long as I'm alive. Being a survivor is a mental state, not physical (unless you're dead). This one case is a statistical anomaly. Sure it's a reality for those folks, because apparently there was no one there in a position to do anything but hide, flee or die. Put a half dozen well trained AND mentally prepared, armed patrons in that theater and the attack still would've happened. But the casualty results may have been altered dramatically.
My mental preparation for the specifics of the circumstance would include being aware of my surroundings and alert to the possibility of an attack (or fire, etc.). I can't get prepared behind the keyboard, but I can relate the underlying ideas behind it here, no?
