I just remember it because when I very first started in my career they told me it would be over if I ever restrained a person prone. If you’re in a situation and they fall prone, priority #1 is getting them supine or side lying with as little injury as possible to all parties.
For a long time I thought cops were just uneducated but alas no. I compared notes a few times when officers would come to serve papers from the magistrate and it turns out they’re only supposed to have the person prone long enough to get cuffs on then they’re supposed to transfer to side lying as well (supine would be a no-go with hands cuffed in the back).
Somehow it’s even worse when you actually and specifically know exactly how it’s supposed to be done correctly both in terms of technique and which situations actually necessitate it. I did get certified to teach at the end of last year. How much good I actually do remains to be seen.
If only all advertising were this honest and straightforward instead of selling me dubiously accurate “vibes.”
