Used several in Judo for 9 years. Choked some out & been choked out. Trained with a guy ( service brat ) that grew up in Japan & trained on grass mats! This guy could choke you out standing, sitting, kneeling, walking, running, didn’t matter, he was awesome!! 😆 My instructor was VERY adamant about not holding it any longer than for submission, be it voluntarily or involuntarily. He was always right there to make sure everyone was ok afterwards. I hated the headache afterwards!
We were practicing chokes on Sunday afternoon [ one of my co workers ]. We hold out to just before passing out then tap out. Everything was just fine after about 15 minutes of working on each other.
I leave to go have dinner with the girlfriend at her parents house [ it was mandatory his 5 daughters and 2 sons attended every sunday, big family dining table sat everyone easily. Feeling fine, having a great dinner some 3 hours after the training.
Got up from the table, got 4-5 steps and without any notice, I passed out. Fell straight back and hit my head causing bleeding from both ears [ not good ]. I woke up to the old man standing over me and asking me if I was okay. Head was ringing like a church bell, serious headache.
Someone had called an ambulance which arrived a few minutes after I came to. I'd stayed laying on my back at the request of the old man. They took me to the local hospital where they discovered I had a severe concussion. Order the girlfriend to not allow me to sleep for at least the next 18 hours. Of course I got back to her fathers place and went up stairs to lay down, telling everyone I understood the risks but I was going to sleep for awhile anyway.
So, when you get someone near passing out in a choke, there can be residual affects if you're not smart enough to tap out before you're nearly out. I've put quite a few turds to sleep on the streets working in uniform. As I mentioned elsewhere, I didn't feel the need to be tap dancing with some asshat who was going to resist my taking them into custody, so when opportunities presented to get the choke on them, that's what I did. And when the life faded from them enough I set them down, rolled them over and cuffed em by the time they could recover.
As others have stated, you hold it enough time until you feel the resistance fade to compliance, or as soon as they have gone unconscious. Hold it any longer than necessary to affect the results you want, looking at potential harming them permanently or killing them. All the chokes I put on people to gain compliance were against academy training rules [ no chokes to be applied under any conditions ] and thus against dept SOP policies. Never heard one complaint from the dept, nor the turds who were put to sleep, but remained uninjured.
Gotta know when the hold, and know when to fold em. They were deemed illegal because most street cops don't know when it's time to let em go.
