ok. so they were there to protect us or prevent a disaster ... ? anything wrong with that concept at all ? maybe

Last time I checked no one knows for sure wtf they were doing there, it's all speculation at this point...

Craft International is made up of combat vets from all branches of special operations. They have been doing training for first line responders, Police and Fire, etc.
