However these genocides seem to take two (possibly three) forms
1. Hitler / Stalin Like a virus they replace the societal leadership function and use the "normal" mechanisms of law and order for their own ends. People are "arrested" and "tried" just like every day - but it is a farce.
Now at what point do you shoot a police officer? When is it socially acceptable to kill a cop? There just does not seem to be a point. So for years this can go on. Rounding up "criminals". I could put psychologists on stage to say "treatment of the whole family" is the solution for criminal activity - we are taking these families to family-re-start camps. You can make up anything for a while. Its only when the media provide proof that this is going on, that people are dying that maybe killing the next cop to arrest someone will be seen as righteous. But you could easily argue that 60 Minutes cannot be aired because it will incite people to shoot cops.
After the cop has arrested you, that's it, you have no guns, game over.
2. Serbia
This is very muddled but basically can be seen as just arrest / herd everyone out of a defined geographic area - for example it would be everyone in the street apart from #47 and #186. Round them all up with an army / militia and send everyone to a processing camp. Thus the removal of guns happens to a whole neighbourhood, and can be done with artillery and tanks. Cant arrest everyone cos they are all armed? Really it seems not to work like that. The mass graves in Serbia / Croatia are filled with military age people.
3. Rwanda. Half of your village attacks your family with knives. Imagine say the white folks in NYC deciding to kill the black folks using pitchforks [1]. This is hardly a controlled genocide so is less crime against humanity than WTF.
I was focusing on the first one - there seems to be no point where shooting a cop (even one in a black shirt) is something acceptable, even for people who would otherwise shoot back.
There is something built into us that perceives immediate danger as a threat, but if danger is kept far enough apart from the "now" we rationalise it away - even if it is bleedin' obvious. Its why i supported Blair/Bush invading Iraq - I mean the guy had a track record, of course he had WMD.
