Who is "they?" You have a video? A confession? Psychic?
Hang it over the Capitol? From a helicopter? Where do you get this crap?
Still waiting for your proof that anyone other than the FBI or DOJ had anything to do with it? Why don't your bring a pallet of lumber, power saw, hammers, nails, and try making and building a toy gallows on federal property next to the Capitol and tell us how it works out!
So, basically what you are saying is that the democrat's security of the capitol is so bad that someone could have rolled up there with an MX missile launcher that day???
