Normally the Capital Police, National Guard and regular troops would fire into the crowd like the Bonus Marcher incident of 1932 with the intent of killing as many as possible. But if the police were outmanned and the troops ordered to stand down and stack arms, I could see a number of congressional traitors pulled out of their respective chambers and hanged on nearby lampposts. It would be an object lesson similar to the Battle of Athens (TN) in 1946. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

I realize you are speaking hypothetically, but such events might arrive sooner than we think.
