As SLF I would like to point out an aspect of this which I don't think has been commented on so far, and that is the reaction of the other passengers who were eyewitnesses to the events; not only those videoing but those visible in the video.
I would say passengers are generally relieved when anybody disruptive is removed from their flight and full of praise for the crew and/or LEO, especially if it means their flight gets to depart more or less on time.
The overwheming impression one gets from available evidence of passengers' reactions in this case is one of outrage.
