Odd thing....perhaps I am a quick study...but every time I got the crap kicked out of me I fully grasped what happened (after I got my senses back anyway)...and there was no training needed to do that. How much training does one need to grasp the fact the Bad Guys are in fact Bad Guys and shall do whatever they can and wish to make you uncomfortable or dead even?
Now just why would any rational person have to be told there is a moral/ethical difference between getting your own ass kicked and kicking some one else's? Where is it written in the real rules of warfare....not the Geneva Accords...where one is required to make nice with enemy combatants who are resisting those tasked with their care, custody, and CONTROL.
You folks sure do have to dig for something to say sometimes!
Or is it I am just missing the finer points of argument here?
