Knowing how to lock someone is useful, but its important to know when its appropriate for.
Personally I figure a lock is only required in any situation where you cannot flee after there is violent contact.
In most cases the best plan for surviving conflict is get the hell out of there as fast as possible.
Sticking around and locking an aggressor runs contrary to that.
So you should only be doing it if
1 - Its your job (eg security, police)
2 - You can't leave the aggressor there (eg home, family members still there etc)
3 - You need this person intact (minimum force scenario, or sue happy rich kid. Spank for good measure)
Now with regards my actual guidelines for locking an opponent.
- Pain in not a reliable factor. Pain tolerance, adrenaline and chemical substances can skew it too much for it to ever be reliable.
- The lock must remove the opponents balance
- The lock must remove the opponents leverage
- The lock must involve a large joint. Small joint manipulation should only be used as aid to larger joing locks. For example, don't try and lock someone by the fingers or wrist. Lock the shoulder and use the fingers for added control instead.
- You cannot lock someone indefinitely. Sooner or later, they will find a way out. Even if that involves doing themself harm, just like an animal gnawing its leg off when its stuck in a bear trap.
Now then we get to the subject of pressure points
- Never bother with pressure point striking. Adrenaline dump renders fine motor skills useless, so pin-point striking chops shall be henceforth reserved for GI-Joe figures
- Use of pressure point during locks follows same rules as small joint manipulation, use as an aid to large joint locks, not on its own.
Any other points or suggestions about these?
