You're being charged with a serious offence.
The recomended action for a Magistrate trying violent disorder on a first time offender pleading guilty is to consider whether he has sufficient powers and to consider sending it to a higher court for sentence.
And a magistrate can order up to 6 months imprisonment!
I think you were rather silly in refusing a solicitor the charge of Affray is less serious and he might have been able to get the charge reduced to this.
I'd suggest you go and get some proper legal advice sharpish I think if you just let things run their course you might regret it
Especially as they'll look at sentencing guidelines here:
http://www.sentencing-guidelines.gov.uk/guidel ines/other/courtappeal/default.asp?T=Cases&cat ID=7&subject=PUBLIC%20ORDER&SubSubject=Violent %20disorder
that say :
Where offences of violent disorder are committed in the context of wider public disorder, it is appropriate to pass a deterrent sentence.
� Such a context adds gravity to the offence and therefore the individual acts by the offender cannot be considered in isolation when passing sentence
Wider disorder and deterrent sentence are the two phrases you need to think about.
Get yourself a solicitor pronto!
