Reminds me of those poor kids and teachers at Columbine, waiting for the police to show up.
Then when the cops showed up, they stood their with their thumbs up their asses.
This is the very definition of terror.
Praying the live one is talking and LE is making progress toward determining what has and is (currently on the ground) taking place regarding this attack. Other possible attackers are being rumored. No confirmation.
Thus far I guess the number of attackers known is two, possibly three.
