On a side note the dodgy photos at the bottom of the link are very amusing. my favorites are photo 9 and 12 Puts into perspective how stupid banning the kid from having his photo taken actually is.
His hair looks fine to me. Short back and sides. However is this how his hair looked for the photo or was it taken at a different time? If he's turned up with a grade 0 then fair enough, you can't trust the press if there's a story in it.
Makes no difference. I one clipped my sons hair to a grade 3. I shaved the back of his neck & realised I'd missed a bit. I forgot to put the end back on so he was left with a bald spot. Only option was to give him a zero all over.
