“Remember the number of devices are more than two that exploded”
My understanding is that there were only two exploding devices. The police evidently did blow up a few packages that they thought might be bombs, but were not. In those cases LE would provide the charge to blow them up to be sure.
OK, missed that on the news of no unexploded devices.
I wonder if the “only two bombs” mantra is one of those little lies that cops tell so they can have a little something to confirm a confession....
