It is an approved method of restraint by that police department.
There was a thread on here about it from about 2 days ago if I find it I will repost it.
Thanks. I missed that one (obviously).
Regarding the approved methods of restraint, see post #1 from the link below.
But as I mentioned there, there is no discussion of TIME. Here’s what I mean. Firemen sometimes use sleeper holds to get unruly people out of burning buildings. But they’d better use that hold for only a very short period of time. Otherwise they would kill the person.
