I'd rather think that depends entirely on your view of the constitution and the rights afforded to US citizens, than what it "takes to kill someone". However, YMMV.that depends entirely upon your conception of what it takes to kill some one.
A gaurd, a gunman, a ditch, and some one to use a shovel.
some paperwork... which I can see being the expensive part, but like I said we are in control so why not make it less of a hastle to do?
certianly not $48k
