He Tweeted, and I quote: "LOL, Fuck Muamba. He's dead."
There's nothing racist in that statement. He might be an asshole, but on what basis are the elements of a charge of "inciting racial hatred" met?
And, no, the UK doesn't have the first amendment. But the UK is a member state of the EU, and the EU's Charter of Fundamental Rights specifically states that:
"Everyone has the right to freedom of expression. This right shall include freedom to hold opinions and to receive and impart information and ideas without interference by public authority and regardless of frontiers."
The mental gymnastics required to reconcile a recognition of such a fundamental freedom with throwing a guy in jail for two months for saying "LOL, Fuck [guy]. He's dead." probably warrant at least a 9.8 from the Romanian judge.
Seriously, this shit's disgusting, nobody can pretend anything even slightly resembling freedom of expression exists in the UK.
