People won't be lining up to volunteer for that.
That takes something you can only expect from paid help with the
equipment, training and psychological support after the fact to do a
job like that.
Without a uniform I would be frightened some fool would shoot me
thinking ( Not without cause ) that I was in to steel his or her
property .
I have served with our army, I have seen death. This is incramentally
beyond what I would want to do to myself. There is no dinner
conversation ( or other civil circomstance ) where this becomes
appropriate banter.

This job will be done and the people that do it will need support. I
for one would not want to take this baggage home to my wife and kids.
I am also the guy that can paint the walls with other peoples blood, It
does not faze on me: But the pure scale of this ............
