I'm rapidly coming to the same conclusion. Cops know more than they are saying. Too much info on the perp(s) too fast. This (these) guys were already on the radar despite the lack of criminal record.
Looks like we’re all on the same page waiting. Kind of interesting too in light of Glenn Beck’s series this week on the potential for a Beslan school attack here in the states. He focused on Florida because of events in the past couple of years.
