Prisons and a few other things

[Timelord]

Nice people? You are somewhat confused my friend!:-) Morality is always a variable standard, depending on an individuals point of view and circumstance. Not caring what others think of you is a tactical error. Being plain nasty for deterrents sake is a viable option but don't forget that being thoroughly unpopular in a locality can lead to unpleasantness being brought directly to your own door and the possibility of a nasty end yourself. All situations need to be weighed up on their individual merits and a response meted out that achieves the objective. Laws of nature do not call for deadly force at every confrontation.
An observation about containment of prisoners during SHTF events, is that it has been seen in recent times in Libya, Egypt and possibly elsewhere, that authorities sometimes release violent and destructive prisoners into civilian populations as a distraction to any self cohesion of the civilian populations and to make them fearful of being out on the streets. Sometimes these prisoners are let loose in an area and other times they are purposfully directed and equipped to target more specific areas that are a thorn in the side of the establishment.
