Read and digest the riot laws then tell me he wasn't!!!
IF a policeman used a baton at a football match dare say there would be video evidence from the cctv.
Quite frankly if you riot you risk getting hit with a baton. Simples!!!
If he wasn't there rioting he wouldn't have got hit.
Oh and as an afterthought Stoo82 is correct in asking is there video evidence he was hit by a baton and if so why?
