In Search of Clarity

I'm working on the manual for talking down EDPs (Emotionally Disturbed Persons) and I pretty much have to do a section on what to do when it goes bad. This will be an e-book, since it is far too short for print publishing. Since it's an e-book I want to avoid pictures. They really mess up the formatting.
Is this description of a figure-four leg lock and seal position handcuffing clear?

The figure-four leg lock is also useful. Any technique used on the knee joint, especially if it relies on pain, will have a risk of injury. To apply the technique you place the threat's left ankle directly in the hollow of his right knee (if I have to tell you the directions can be reversed, you probably aren't bright enough to be literate anyway). The right knee is then flexed (bent) which both traps the left ankle and puts pressure on the knee such that it can be snapped.

The farther towards the toes you apply pressure, the better leverage you have. Many threat will be able to simply kick you off if you don't apply good leverage. Almost all will be able to kick you off if you try to cross the legs at the ankles instead of putting the ankle directly in the knee joint.

You do not need to control this hold with your hands. In the example above (right knee locked, left ankle trapped) I kneel with my left knee outside of the threat's butt, the threats right foot in the crease of my thigh and my right ankle hooked behind the threat's trapped left ankle.

I learned the hook trick because the only person I've ever had escape from the figure four was a very small, wiry and quite dangerous mentally ill female who had a thing for stabbing people. She just did what looked like a military low crawl and pulled herself out of the lock.

This is an excellent unhandcuffing technique and a very good hands-free control hold. If the threat will not give up the hands for cuffing, if they 'turtle,' you can reach under their face (fingers flat to prevent biting, just like feeding a horse) and use the pressure point under the nose at the base of the bone to extend the spine. They will put their hands on the ground to support their own weight and you can simply yank one of the support hands back for cuffing.

After experiencing this, most NTs will voluntarily give up the remaining hand. You may have to do it twice for EDPs.

'NT' in the above paragraph means 'neurotypical' short hand for not an EDP. It's explained elsewhere in the handbook.

Clear enough to do?
