I'm just working on one of the tones I'm hearing from the U.S., "What can you (I) do?"  And I suppose I'm thinking that these videos (of one incident) will make people think: "The first thing is, ponder what is 'beyond the limits' and ponder how best to act if and when such a situation occurs."  Each will have their own way, but if everyone has...that look in their eye...that says, "I know the limits, and if you step over them I'll act"--

--but always always with a sense of DE-escalation.  We don't need any more wars or people adding punches, but self-and-others-around-you protection...ach...maybe this comment explains it a bit better:

I read in something extra here.  I read in that the disassociation (the lack of contact--SOLIDarity) leads to the individual isolated and therefore a step behind the action. not confident to act because..."What if I do the wrong thing?"  And I suppose the social message: "There IS a wrong thing, and if you do it you are bad and will get what's coming to you."

I believe the police have a name for the situation where people they pick up for questioning will start admitting to things irrelevant to the enquiry.  A friend years ago was taken to a police station because the police suspected that someone on the coach had been involved in a fight at a nightclub (they were all travelling back.)

"I just started feeling guilty," he said.  "I thought of all the things I'd done wrong."
