You haven't said anything fundamentally different to what I had earlier. Again with regards to kicking a man (in the head) when he's down. Like I said before; if kicking a person's head is the only 'technique' I have to prevent that person from remaining a threat, then I haven't spent my time learning aikido particularly well. Indeed I can't ever recall any shihan either from Japan or more locally teaching a kick to the head (for any reason) least of all for the reasons given earlier in this thread which were; IMO daft. ..Kicking someone in the head when they're down is nothing short of thugish behaviour and given that we're supposed to be martial artists training ourselves to be able to control others under arduous circumstances, letting fly with a kick to the head when that person is prone doesn't sound much like 'control' to me.
