There is a quite amount of techniques in aikido that in the end contain pinning. I'm interested in your opinions what the characteristic of effective pinning in aikido are. Are they the same as in other Budo arts or fighting sports?
Recently I watched in TV how police in different towns evacuated protesters from parks, and sometimes it was needed up to 5 police officers to pin and transport one protester (who of course didn't want to gladly cooperate). In this light, how you see claims that in aikido you can pin somebody with one finger (or even one hand)….
Again, please no IP/IS nonsens discussion here.
Basically I would say they share a lot with other arts ways of pinning. Aikido can focus more on the energy though.
I don't need t'v' to see such things as you mention but we most remeber something here. Practice, refinement, more practice, more refinement, a process. You could say that first when learning pins it's the how to's and practice but what does it show? It shows it's possible.
Then when you come across a more uncooperative person and find you need to improve you then have to practice more and refine it more, and on and on. Until you may become an expert at pinning, a master at pinning where it doesn't matter how uncooperative the opponent is. It's all a process and the same in any walk of life.
So someone in Aikido who is that good could make it look easy obviously.
Your final question on one finger, as per Tohei maybe in the old american documentary. Well you would have to lower your parameters on the thread for that one now wouldn't you. It's not something the average joe can do and would venture into the deeper Ki aspects at least or even into the field of pressure points in another art maybe.
