A few minutes later LEO's came on board and eventually had to carry her off the plane. Then the rest of pax applauded. Any video taken of that incident would show a screaming, belligerent pax with whom the crew made multiple attempts to calm down before they escalated and multiple attempts by the LEO's to persuade her to leave on her own 2 feet before they physically removed her. She was put into a squad car on the tarmac after being taken off the plane.

Not every forced removal is comparable to what happened in this case.
