He's not exactly helping the 'cause' of those (nudist/naturist) folk who do keep themselves to themselves, by and large. Militant nudity! Who'd have thought that would hit the headlines in the 21st Century? Eh?
I think you're spot on though, Stu. Proper psychiatric care is what this bloke would have benefitted from, not 'punishment' - that appears to have spectacularly failed in his case - he's now found "martyrdom" and that's a very powerful force, indeed. I hope the authorities 'wake up' before he's released next time - might be in their interests to deliver him to his own door, as for sure, the media will be camped out on the prison steps when the time comes...............
