What problem? You must be the only person in the south who still believes that Palace fans had weapons. The tv, radio, local press, national press have all said the police got it wrong and there were no weapons.
Because there was speculation about the alleged offence, which he was cleared of. Likewise when Rohan Ince was arrested, and then found not guilty.
Nobody has even put the link to the Evening Standard.
Believe me, I've had a look on Twitter and there are 23K tweets about it.
