The problem is they went to a community they are not part of, with weapons, seized a building, and issued ultimatums. They did this with a political intent to cause influence on the federal government. This legally is a act of terrorism. Agree or disagree with the message, is moot and the local, state and federal governments cannot allow this to take place, as it will happen everywhere over any thing.
I actually agree that the federal government has seized lands, that they shouldn't have, that these"ranchers" have legitimate grievances. However, the method they chose was foolish and only left the government two options. 1) allow them to leave peaceful and arrests them at a later date (this method has been attempted for several weeks with no success), or 2) arrest them through force (the current attempts taking place).
What will likely take place now, is the "militia" will dig in and ready for a fight, they will be emotional about the killing of one of their "leaders" after two-three days a few will realize their situation and bailout in the middle of the night. A few will remain. The FBI will wait a few more days, allowing the small remaining group to weaken their defense's, become more complacent, and than they will conduct an assault. Those who give up will live to face life in prison, those who fight will die.
This ain't the first rodeo for the FBI, they have evolved and learned.
These "militia" members have one last chance to make it out alive and face some criminal charges. If they don't they will be fucked either way. Ball is in their court, play stupid games win stupid prizes.
Called it...lol
