Basically you're saying the military should have impunity and the ends will always justify the means. That's a pretty messed up way to think.
You are mixing apples and oranges, what he did while on tour of duty, has nothing to do with what he did at home. And infantile would be the mind that would equate on Jesse Ventura with a category of Hero! His character is far from reproach, so please go gently there, Ventura served in the 70's, certainly not in operations anything remotely similar to Afghanistan or Iraq.
While we are on the impunity subject, I would ask if you ever served? Or are you a political hack that thinks you can armchair a military operation while sitting in the comfort of your living room? There are strict rules of engagement when conducting an operation, you think it's like the movies? Run around and shoot whatever the **** you want? That you should be able to shoot the gun out of someone's hand? Don't use flame throwers while the enemy can? You want to hold men who are in harms way to a higher standard than those wishing to do them harm? I remember when we (the U.S.) families were sending better ballistic plates to our servicemen over there because the military couldn't... Needed because the insurgents were using armor piercing rounds against us, but we couldn't because they'd go through the block/brick walls of houses the insurgents were using... Potentially causing collateral damage and possible casualties.
Politics has no place in WAR, its an ugly, dirty business and too many of the sheep here would never stomach seeing the carcasses of wolves devoured by the sheepdog. After all the wolves were gone, the sheep would turn away the sheepdog, wondering if they'd be eaten too, just never really getting it, so fearful of even its own shadow, it would turn on its own benefactor. While many think they can sit and judge, they have no place doing so until it is they themselves that have stared down the business end of someone wanting to end their life... Doesn't matter why, just in that moment of when your existence could end...
Anyway, try that for 4 tours, under constant threat, stress and perform. Let us know how you're doing when you get back, don't forget to send postcards while you're over there. Until then, just enjoy the story for what it is, and what it isn't...
