Sputniks knew the risks he was taking when he did it near enemy territory. Like it or not, this can't be argued. Why? If he wanted to do the run and not have the possibility of being shot down, he would have simply gone further behind the front lines.. not RIGHT on top of it. Grizz somehow located him, which the odds were against that as well and had every right to shoot him down. You and I might have chosen differently, but this was not any one's choice besides Grizz's. The only thing I could fault Grizz for is "owned" comment. We can see this by the pictures, no need to rub salt in the wound.
