Some people think the video does not look real. The bicep on the right arm does look strange. One commenter claims the video is computer-generated.
The body, as seen in the video, had been hanging there for a number of days, as I understand it.
So, here is a before-death photo (early on in the Crucifixion process), and then you can compare this photo to what happens to an obviously normal looking human body, after it has been crucified and left to hang for a few days.
In my opinion, the above photo removes all doubt.
It is normal to not want to believe what we are seeing when we look into the face of extreme evil.
This natural aversion to belief in extreme evil was one of the mechanisms which caused us to allow the Holocaust to happen.
Let us not do this with the Holocaust that the Muslims of the world want to commit against the Christians and Jews of this age.
