Yeah, I thought of that as soon as I posted. But Shep also said people are LOCKED INSIDE the convention center. There's no way that's true.
I thought they broke into the Convention Center to begin with? If so, I'd be surprised if someone was locked in, unless it was in a room or something.
no, to be fair, he did not say "locked inside" - he said that roadblocks prevent them from leaving the area via the roads.
