Ever heard the expression, "sitting duck"?
A fairly famous piece of footage from Aussie TV shows a debate between a number of "personalities", including radio redneck conservative Ron Casey and Normie Row, a 60s pop star who got drafted to the Vietnam War purely as a political stunt (his number didn't really come up in the lottery, he was hand-picked for political gain and our biggest pop star had his career killed) but who did his service and is proud to have served his country, even though people like Ron Casey hadn't been very welcoming or supportive to Vietnam veterans, not considering it a 'real' war. They were debating on live television the upcoming referendum on whether Australia should become a republic.
Scene set.
Ron Casey made a point in the debate about fighting under the Australian flag and Normie Rowe replied that HE had fought under the Aussie flag and would happily have fought even if we had a republican flag; Ron Casey made a disparaging remark about "that was only Vietnam" or similar, Normie got heated about it and got out of his seat, walked over to Ron. Ron waved dismissively from his seated position; Normie shoved him. Ron launched out of his seat and knocked him off the platform with one, single, mighty punch. Next thing the pair of them are going at it, on live television.
It happened within a second, they had both been sitting down to begin with. They were both experienced with the media (therefore less likely to physically lash out especially while cameras were rolling), generally both very easy child (in every sense - well, at least Normie Rowe) but this escalated too fast for anyone to prevent.
A raging difficult child, especially one who is less tuned to social cues, is not going to be thinking about the morality of attacking someone who is in a more vulnerable (and less threatening) position.
Sitting down - absolutely no likelihood of it being effective as a deterrent.
