Mate,
Courtney is agreeing with you, just disagreeing with the tone of your sign off which can read as 'let's sink to their level'. I understand your point though.
He and you are saying exactly the same thing, that mil aircraft engaged in rescue operations are permitted to be toting (and using) any self defence weaponry they want.
Your example appears to be addressing a different subject. You cite the reason for the death of the hero you name as a General's decision - nothing to do with whether or not MEDEVAC could defend themselves. I am unfamiliar with the story so don't know anymore than what you've posted.
Let's not forget that one can act in self defence of others, applicable in the case of an escort aircraft with a MEDEVAC.
