Agreed! I love etymology and I've always found British slang quite intriguing, that's one reason why I enjoy reading The Sun so much. If one can get past the 90% trashy content they occasionally have a really good article, and it's quite often imbued with numerous slang expressions. The fact that they have been consistently and unashamedly pro-troop and supporters of the war on terror doesn't hurt either :-)
The Sun frequently uses words and phrases drawn from Cockney Rhyming Slang, one of my favorite slang forms. It was originally developed by criminals so that they could talk amongst themselves without the police understanding what they were saying!
If you ever get 'stuck' trying to understand what they're saying, numerous British slang dictionaries exist on the internet, but I haven't found one that really stands out....even at the BBC. They are all lacking, probably because the slang expressions change frequently.
A high amperage rectifier attached to the "security" fences would help a lot.
So would perimeter guards with shotguns, pikes or billhooks (forgot for a moment this is Britain) instead of CCTV cameras.
