I want to know the answers to all of these questions, but especially #7. 

As for #1, I think OPB reported that 8 people remain, and "are committed to staying." Unfortunately, FBI involvement might fuel the fire for like-minded militia members, but something needed to happen. I see this entire situation as beyond ridiculous and pointless, but I hate that it's led to bloodshed. Like most people, I just want it to be over, without inciting any copycats.
