ummmm - // Andy - wasn't Shipmans motives for financial gain? //
Not in all cases - the perceived wisdom is that he developed a 'God' complex, and simply enjoyed the power of life, or actually death, over his patients.
My use of Shipman is an illustration that not every psychopath is picked up by analysis, for example, by tests for fitness to own a gun.
I am willing to bet that, had old Harold been a shooting fan, he would have sailed through the tests undetected.
But that actually point I have tried (and thus far failed!) to make with Retrocop, is that is assertion that NO-ONE (his caps) in his gun club would go on a rampage is simply not a believable statement, because anyone at any time can go on a rampage, with no warning or prior evidence.
It's a simple point, but it got lost in the red mist when Retrocop read it, and he went off on one.
Tomorrow is another day, hopefully he will have calmed down and may want to come back on the point I made.
