VANMAN,
You have missed my point.
And in the case where the aircraft ignored the RA, it was FULLY UNDER CONTROL. Both had traffic, the descender was stopping above the climber, which was stopping at the level below. Both understood the plan. Their TCAS' wanted them to cross levels by steepening the dive/increasing the climb. How can that be safer?
Surely jumping in at the TA stage, having your situational awareness on the job, and controlling the situation is better than blindly following an unexpected RA? Not always possible, granted, but preferable. What I was getting at is the UNCONTROLLED way in which you opt out of the ATC system at present. I haven't put a lot of thought into the solution- maybe a button like the ident which you could hit at the same time as reacting to the RA which would announce to all, ATC and the other aircraft involved, that you were RAing?
