It really is not just as bad to not pay tax or fulfill the other duties of an employer. Accusing people of keeping slaves (with lurid details such as dog kennels, beatings and starvation) is a lot worse than not paying taxes, etc. When you accuse people of keeping slaves you put them beyond the pale and paint a picture of people who have absolutely nothing in common with the rest of humanity.
Emotional trauma counts, but it doesn't pack the punch in a headline that 'SLAVERY/STARVATION/BEATINGS' does.
Yes, there have been several other cases where raids have netted workers whose tax has not been paid, and charges have been brought, none of which has resulted in a guilty verdict yet.
Yes, by calling security they are being treated differently, and this does not matter because the running of the clinic and the safety of the staff cannot be jeopardised for the sake of all the other patients. To refuse to call security just because this would amount to different treatment would be akin to refusing to call police for the rioters. Security personnel are there because some people and situations warrant it.
From the C4 report (featuring rather scurrilous and dodgy editorial values btw), right at the end -- 'It is only now with the change in the law that they [police] have been able to act'. I presume this is a reference to the inclusion of emotional trauma as a reason to involve police in the phenomenon of people who have possibly not worked a day in their whole lives suddenly finding themselves working all day? I find it surprising, and maybe some of the men themselves find it surprising, that some of them now seem to have relatives and various social service agencies willing to take notice of them, after they have been allegedly off the radar and forgotten for several years. There have been no reference to missing persons reports filed on behalf of these men over the years. C4 made nothing clear really, except that there is no longer any presumption of innocence until proven guilty and the media can say anything they want about Travellers. Funny to hear the report talking of people who might otherwise be described in terms analogous to wastrel or nuisance categorised in the report as 'vulnerable', roses born to blush unseen, etc.
According to the local Basildon press, police have heard allegations about slavery or people being held against their wishes at Dale Farm for years and have decided that the neighbours were crying wolf.
