Can I point out that it is a tad discriminatory to attempt to distinguish between 'Romanies' and 'Travellers'.
There is much to be discussed about the practical differences (if any) between those claiming to be the former and other itinerants, but makers of programmes like BFGW cast their nets wide enough to include all Travellers in their vitriol spray.
Nowadays, the main difference between the various groups is that Travellers as a whole have yet to receive official recognition as ethnic groups.
