They could be brought to court for whatever they did, that's the problem, you don't have any evidence on this individual. You can't tell if he was a bystander or an attacker. Because Israeli troops have destroyed all memory sticks and recordings. You can't tell if the soldiers have fired those shots to save their lives or the protestors had pull their knives to do so. If the police shot me in the head from point-blank distance and destroyed the evidence afterwards he'd go in for life. Death sentence in many countries. It's a clear show of guilt.
Fortunate for you, they lack the balls I posess.
And bulllsh*t excuse from you, you've launched a large scale operation for the life of a single soldier.
