He should have hired a lawyer. The e-scooter is a slam dunk, but the obstruction is dodgy. The Scamerati driver was quite capable of moving his van or requesting that the guy moved his van, because he was causing obstruction. If he was not warned, it would be hard to prove the obstruction was wilful. Section 89(2) of the Police Act 1996, is a stretch to apply to the view of a mobile video camera. There have been plenty of other cases, some went to court (guilty plea), some didn't. It's all about the representation.
I haven't seen the video though, so they may have warned him.
