Ok whatever.... you brought up assassination and went there but lets move on. What was the collateral damage you speak of here?
Explain to me how you would have handled that different. These guys were under-fire. They saved 11 kids. The mission was to capture this fuck. He runs down a tunnel with his 3 (you pointed out 'brown' for no apparent fucking reason) children. Now, what are we supposed to do? Negotiate? In what f'ing world is this guy blowing himself up with his own children collateral damage on the part of our troops?
Collateral damage need not be under friendly fire:
