This is so much more than taking over a building. This is a challenge to the current administration to see if they have the stones to forcibly take on gun-owners and if so, how much bloodshed and death they're willing to accept. Because if they call in the national guard or SWAT to try to take back that building by force, there will be hundreds of casualties. I believe the military and police would be reluctant to step in as neither supports the current commander in chief. This is a big fuck you to Obama and basically calling him a giant pussy, which he is. I suspect he'll overreact and show everyone what a mandatory confiscation of guns will look like: A bloodbath that results in the US government backing down.
