This is one of the things that I can watch on a sad day to immediately be cheered up — specifically the moment when the radio presenter gets flustered and shuts them off when they start swearing.

Strongly recommend it to anyone who hasn’t seen/heard it. Here’s a link to timestamp in above video where this happens:

“Get rid of it! Sorry, we needed to get rid of that, because that suddenly, uh, turned into something we were not expec— well we were expecting it, and we asked them not to do it, and they did it anyway”

As someone who frequently falls and needs help to get up, I know some amount of what people learn in “lifting and handling” training; it’s terrifying how many people will attempt to help me up in a way that’s dangerous as hell (I know someone who had their shoulder dislocated by a supposedly trained person doing a “drag lift”, which is something you should never do). I don’t expect regular people to know this stuff, but I do expect people whose job involves first aid and stuff to at the very least know “I should not attempt this unless I have lifting and handling training”. It’s horrifying to see such ignorance.

However, this is nothing compared to what you describe — the difficulty and danger involved in restraining people (as opposed to helping a cooperative person up) is a wholly different challenge. All the more reason why proper technique is essential.
