Sorry to harp on about my Prison Visiting years, but in the Visit Room, the rapists and sex-offenders on Rule 43 (sometimes called Beasts by the other inmates) were marched in escorted by several officers and seated in a separate corner of the Visit Area. 'My' prisoner at one time didn't like what he called 'Pikeys'. (I'm not being racist, it was his word, not mine) But even he said once 'The Pikeys in here have nicked stuff or done GBH. I don't know of any Pikey Beasts'. This chap had been inside in many jails for a total of 16 years, so his view is probably worth something. I might add that travellers were not very numerous in the prisons I visited. Drug offenders, dealers, burglars on drugs etc made up most of the population, and they weren't travellers.
