Perhaps you need it explaining. My comment was meant to be ironic, not a statement of fact. It was actually meant to be a play on the person-in-question's presumed 'innocence-until-proven-otherwise' rather than an accusation against others. They can sue me if they like...they won't get much, sadly!
I doubt they could, since you didn't mention anyone specific. I was just pointing out that libel applies to everyone, not just celebrities.
