I was reading through some books again and came across an interesting defence. The shove. The idea is to create a suitable gap between you and your opponent, when followed by the right verbal commands, it can trigger the flight response. This sounds/looks like a reasonable idea as it can cause minimal injury (unless they fall over and bang their head) and looks great for witnesses and cctv. The downside would be that it would perhaps only work for those in the "undecided*" phase of pre-fight. Standing square on, giving it plenty of verbals. The other point comes from McCarthy's "habitual acts of violence" (haov), which indicates that a common "attack" is when a person is pushed then retaliates, usually with a puch to the head. Thus, if you only push someone, not shove them, then you are only going to trigger an attack. Another point come from conversations with those in the states who say a "football" tackle is also a very common attack, thus if you push someone away, wouldn't this give them the range to try this effectively? Personally I've never tried it. Thoughts?? *this term is my own opinion.
