"I was just like, if you didn't assault me, what was your finger doing in my mouth."
This is why camera boy needs a lawyer to speak for him.
"Do you want me to just run you off the track instead?"
This would/will work very well for Mr. Fat in court. Whatever happened after that point in the incident is in the context of a threat having been made to harm Mr. Fat.
My take is this. Fat Man gave way, in his own time, only to have Camera Boy run into him, thanks to following too close.
Considering Camera Buy had issued a threat to run Fat Man off the trail shortly beforehand, Fat Man is remarkably calm about this, and when asked what he is doing, (which was freaking obvious), he tells Camera Boy he is letting him go.
That should have been the end of it, and Camera Boy should have gone on his way, and should have said thanks.
However, Camera Boy loops round intentionally to continue filming Fat Man, seemingly with the intention of confronting him, (and presumably hoping to get some nice video to upload to YouTube later to laugh at with his mates).
At the point of this confrontation Mr. Fat, who has been goaded twice by Camera Boy, gives him a piece of his mind and wags his finger in Camera Boy's face.
Camera Boy, in full knowledge of the law he previously ignored when he threatened Mr. Fat, tells Fat Man that his finger wagging is assault, and underlines he has it all on camera.
Mr. Fat, fearing a stitch up, decides to go back and get hold of the camera. A mistake, but one that should be considered in light of blatant provocation.
No assault by Mr. Fat is evident.
Unless the nearby cyclists witnessed it, I would doubt anything comes of this.
The only evidence of any injury is to Mr. Fat, witnessed independently and admitted by Camera Boy as his work, regardless of how he suggests it occurred. This is potentially a case against Camera Boy, but I doubt Mr. Fat is so petty. He lost his cool, and I would assume he regrets it and would rather not hear about it again.
As for the pricks who think the trails are made for them, who reckon they can wind up people they do not know and film it all. Well, hopefully they take holidays in Scotland.
If it were me, as soon as I heard the git threatening to run me off the trail I would have stopped and tackled him on his 'trail etiquette'.
