I saw the video of this, and it is TOTALLY in-excusable.
It's a very sad state of affairs when this is deemed acceptable by a (any?!) society, and a PM is calling for a pardon.
Anyone watching the video will see it was cold blooded, calculated. He was clearly stopping the ambulance which was arriving that moment from treating the guy. He was reported to have said (by his own colleagues) that the guy "deserved to die" and had had to be calmed down by same said colleagues.
It was a defused situation, with a wounded assailant who had prospects of being treated and fairly trialed for his crimes.
Comparisons to the Blackman case are incorrect, the situation is was very different. It seemed (although it is hard to find statements from the soldiers that had attempted to treat the wounded man) that the wounded party in this case was probably too far from professional medical care to actually survive. He was also in an active battlefield situation, and under a very different set of circumstances.
I am not saying what he did is right, and not defending his actions, also when you read the full account, there is proof of other abusive behavior towards the wounded soldier.
Both cases, the shooters were clearly in the wrong, and both cases, they deserve to be punished. However, there are clear differences in the situation that should change the sentencing imo.
I don't want a judiciary system that is fair and balanced to terrorists - I want one that's going to crush them under our heel!
Then they get exactly what they want. Treating them like that creates a cause, and breeds a new generation of terrorists.
This is exactly why Israel and Palestine will continue to rage for generations.
