Regarding this Trauma prog, I've only ever seen bits of it, and I wondered how they get the permission of the people they film... I'm guessing they get it afterwards, but what if the person is really pissed off they got filmed at all, and that the film exists of them all smacked up and half naked on a trolley? I often wonder about this with those fly on the wall things, especially when people are getting arrested - some of them don't have their faces blurred, and I could never work that out. It must be either that they have agreed to have their face shown on telly, or they had no choice in the matter as their face could legally be shown once they were convicted or something. Does anyone know the deal?
