It is going to look like a punch on a crappy security camera. And for an armlock it will be off the bat without what looks like provocation.
No, I don't think so… it's quite clearly both hands to the outside of both shoulders… not like a punch at all. As far as "off the bat without what looks like provocation", the technique we're looking at is largely a security hold… in other words, it's applied by security personnel (bouncers, security guards, police etc) in the course of their work… particularly when dealing with persons such as bouncers, it's at their discretion when they want to take physical control (before it gets really violent), and, as it's really not a violent act, it can easily and justifiably be used against someone who's getting 'mouthy'… which is all the provocation needed.
You can just shoot for an arm drag in op video and from front on looks a bit neater and you really have the arm secure.
The problem with an arm-drag is it pulls the other guy towards you… and can easily result in an instinctive immediate launch of an attack. Turning them prevents that. Additionally, an arm drag isn't that secure compared with the video itself. If you're talking about the clip you linked, it is an arm drag that's applied… and that takes longer for the guy to get control of the arm.
You can even turn a guy with an arm drag and get into that goose neck. The cross body push just looks like it will open you up and has a higher risk of loosing the arm.
You'd need to realistically drag the opposite arm, otherwise you're opening yourself up to others around you (which doesn't happen in the shoulder-turn)… at which point, you might as well have just done the turn. As far as the push/pull opening you up more… no, I'd disagree with that. If you miss the arm (it's easier to miss with an arm drag, honestly), the other guy is in front, with their back to you… which makes it harder for him to launch an attack… whereas, if you do an arm drag, they're facing you, in range, and able to attack. It's not the safer plan.
I will try it on one of the guys to be sure. But they don't give me an even break with these things and chances are they will just pull out of it.
Cool. Just make sure you have a clear understanding of the role-playing necessary for you to genuinely test it (scenario-style, really). If you both have the idea of "I'm going to try this, you try and stop me", that's actually not realistic. But if you do it with "hey, I want to see if this works against a 'drunk, abusive guy' (which is the real world way you'd do it), can you play a drunk guy for me?", then you've got a better chance of understanding it. Ideally, the other guy should be so intent on being abusive that you can apply the turn and hold before he realises you've started to move.
With the figure 4 I am not really going for a lock just getting hold of the arm.
Cool. I'd suggest that it's still a bit convoluted for that purpose, though… you just need to have control of both the upper and forearm, that's all.
I struggle a bit with using pain compliance and would rather just mechanical force them out. Using pain to torture them if they have upset me.
Yeah… not sure that I'd agree with that… torture ain't that cool. The thing to remember about pain compliance is that it's best used against non-adrenalized (typically non-violent) persons… and is used just to motivate them to do what you need them to do. If you get into the realm of torture, and having the target "upset you", I'd suggest calming yourself before getting to that point. And, as far as just using mechanical force… there's always someone stronger…
Most people don't need to be hurt at all just held.
True. The pain is a heightener to the technique, should it be needed… I use it as a suggestion-enhancer… "We're going to walk forwards now" "No!" [pain] "We're going to walk forwards now" "okay…"
I might point out that, particularly in the first clip I posted (which is the only one really dealing with the subject of this forum, actually), the physical technique is only part of it… the other, essential, aspect is the negotiation once you have the hold secured.
The figure 4 is sort of backwards. If I put it behind their back it would become a kimura not a hammerlock.
Oh, I got that. We call it Gyaku Oni Kudaki (Oni Kudaki for the 'standard').
I mostly don't even take the wrist much anymore.
I don't think the wristlock walks them any quicker generally.
True… of course, it's not meant to… it's meant to encourage those who don't want to walk that it might be a good idea to go along…
