Jonny I dealt with bomb threats when I was in the forces, and that is the whole point of bombs, to become feared, notorious. when we got a phone call about it (and believe me, someone ALWAYS gets a phone call when a terrorist is going to set off a bomb), we'd ask them WHO they were, they'd always tell us, and we'd ask them why they were doing it, again they'd always tell us.
no bombings happen without someone knowing it's going to happen. most of the time the threat of it going off was normally enough... once upon a time the threat of a bomb used to make the news... these days.. not so much...
I seen the video of the boston explosion last night, and while yes it is tragic what happened, all I can say speaking from experience, is that they were lucky it was only a small explosion, it could have been a lot worse. looked more like an IED to me.
anyway. this world sickens me sometimes,..
