If you are suggesting I have a bias... the article is from the SCMP ... the video is... the video...
If I was the judge... well no... if I was the prosecutor... and the police brought this video to me I would have tossed it in the bin and told them to stop wasting my time and go find the man who punched the victim in the head.
Progin very obviously did not purposely enable this assault. He appears to be trying to take photographs of the incident and happened to be between the door and the victim.
Why Progin was charged and why this has made it to trial is beyond me.
Meanwhile dozens of triads who beat the daylights out of innocent women in the MTR some months ago (and whose faces are on video) have not been apprehended. Surely dealing with that should take priority over arresting an elderly man for taking photos?
