In the frame

I wonder what the legalities are these days of showing, well, intruding on the public in public places. Especially just to 'help' illustrate a story.

Today on the BBC news I have seen two sets of unfortunate folk leaving their place of (now ex-) business carrying their careers in a cardboard box.

I presume they gave permission?

Oh, and if any see the crew of an entity that is 'uniquely funded and hence does not have such work/life concerns as others' shooting outside, I wonder what the odds would be of getting featured if you write 'Nice one Gordon' or 'You're next!' on the side?
