"but if 14 people say I was in the pub with them, then what? "
Then, raysparx1, I'm afraid to say, your wife or children could possibly be arrested under the Obscene Publications Act or in the case of 'BB' mentioned above, the Public Order Act.
Thus your 14 'invented friends' would be guilty of perverting the course of justice. That's a real test of friendship, eh?
Unless of course you were to fess up, and take the responsibility of your actions.
This is of course, an entirely 'what if' situation, and is not meant to suggests anyone here is guilty of any offence.
HTH?
