Reporters Without Borders (via Harry's Place) calls Iran the "world’s biggest prison for journalists."
Iran's the same country which employs Lauren Booth, the journalist who maintains that Gaza is the world's largest prison. Her claim to fame is when she sailed into the strip last year vainly trying to prove it. This so-called "journalism" won Booth a Dishonest Reporter Award.
I don't see her spearheading any "Free Iran" efforts.
