Boggling indeed. Just what sort of crime do they think someone is going to commit with an old Bren or SLR flash-hider? 'Old Lady Brutally Mugged With Gun Flash-Hider' is certainly a headline I've yet to see.

The merciless Mugger may well want to go to all the trouble of paying for an SLR, then removing the F/Eliminator & Hieniously poke her in the eye with it! ( I wouldnt be suprised if that would have been a Police logical response!)
