The Capitol police had been boxing demonstrators out of various corridors and corners of the building all week long. The occupied space shrunk continuously through the simple tactic of clearing people out of a section “for cleaning” and then marking that section off with police tape and posting police to guard it. The order to vacate the building in whole was finally delivered on Sunday, but with several hundred demonstrators inside, the police chose to let people stay but locked newcomers out. And so the attrition began.
