I really must use :) and
more.
Did anyone notice my remark about bringing them to the dog pound?
(Yes, I noticed the laughing gas remark.)
I, too, am concerned about erroneous executions, as frequently mentioned , but
given cases where proof is indisputable, society has a duty to itself to permanently remove such miscreants from this earthly sphere.
I don't go along with the notion that execution is not a deterrent. This might be true in some cases, but I don't think that's the norm.
One of the problems is that "cruel and unusual" shifts with time. I am thinklng of the Gary Gilmore execution by firing squad in Utah, where the condemned person actually chose that method over the other possibilities. Yet much polemic was generated over the "cruel and unusual" aspect despite the fact that firing squads were not at all that unusual. Messy, perhaps, but not unusual at all.
And pretty much instantaneous to boot, removing the "cruel" part from consideration.
