Assume that the state not only allows concealed carry, but mandates it of every single adult who is not physically disabled from shooting a firearm (blindness, inability to move arms/hands, et cetera).

How does this happy circumstance prevent a suicide bomber from accomplishing his deed?

Last year in a Israel supermarket, a bomber set off a small bomb, meant to attrack a larger crowd so he could then set off his BIG bomb. A woman shopper pulled out her concealed handgun and blew his brains out.

There have been other cases as well, where a bomber has given himself away before the bomb goes off.

Next question please.

OK. In other words, you are relying on the bomber's operational ineptitude.
