I don't buy this script at all. I think its fear porn bullshit. The white house is well defended, and short of a nuclear strike I don't see anyone being able to take it down or burn it down. POTUS has substantial forces at his command, and we know from Q they are on high alert.
I got to wondering if this little episode might not just backfire on DC. There could be a push to remove DC's electoral vote, as it used to be. There could be a push to make it a federal government zone rather than a residential city with a mayor, etc. In other words, back to being completely under federal control.
