Interesting thought, Grampa Dave. You could very well be right about that. I had read on FR that some felt it was unusual for bomb-sniffing dogs were used to sweep the area before the game started. If that is true, then perhaps the FBI and HLS did have information prior to the bombing. I'm hoping we will learn more as I do believe the public has the right to know if this was in fact a terrorist attempt.
My trophy wife and I were on vacation and didn't get back until Friday. The Fox News story banner kept saying that the Terrorist Threat level had been raised, and they never said why.
Then, PKM told us about the increase security at the game before the fans even got in.
