The correct response to the bombing of the Boston Marathon is for more Americans, including me, to get off their fat asses and start running marathons.
I have grown tired of both the calls for less "bomb control" (among other things) and more "security measures" (that don't make us safer but make us less free).
Run towards the danger and demonstrate you are not afraid. Inspire the cognitive dissonance of terrorists who will be left with nothing to do as a result of inspiring the opposite of their intended result.
Seriously. After a decade of this kind of "debate," shouldn't we "get it" by now?
