I haven't seen it, but guess that someone praying Namaz in public is being harassed? You don't think that it is reaction and not action? The infamy is not due to this single video, but because of media in past 15 years are so.The video is showing the opposite!
You are being far too 'by the book'. Sitting on a sufficiently wide pavement for few minutes doesn't hurts anyone.But it is. Nobody has the right to block a public right of way.
