I don't believe the Israel claim until I see by my eyes.No problem, I understand, I'll try to write it more simply.
The Israeli soldier executing the man was seen on CCTV and had official reports, the attack done by a different group (the two palestinian teenagers with knives) was also captured on CCTV and had official reports.
You didn't believe the two Palestinian teenagers were guilty, but you believe this Israeli soldier is - why?
What we see that two Palestinians men wounded lying on the ground,and a soldier executing one of them.
So if they already shoot (neurlized/freezed) ,technically they were under arrest to be taken to the Hospitale .
