Principles of pinning
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.
