I wonder how many Boston liberals spent the night cowering in their homes wishing they had an AR-15 with a hi-capacity magazine?Yes, he really is that stupid.
To answer your question, Rep. Bell, none. Bostonians don't cower, liberal or otherwise. They followed the instructions of the authorities to stay in their homes so the police wouldn't have to worry about the safety of the law-abiding public, and so they could concentrate on finding the S.O.B. that perpetrated a terrorist act.
It was Senators from your party that made it easy for terrorists such as these, and other criminals, to get guns without any background check. Or maybe you forgot that already. I can tell from your Tweet that you're not the sharpest knife in the drawer to begin with.
If you think any citizen would rather confront a determined, gun-wielding, explosive throwing terrorist than have a trained SWAT team do it, then you're a bigger idiot than I thought.
My suggestion to you is to stick to worrying about naming post offices and leave the real legislating to people who have a grip on reality.
