Seriously though im pretty experienced in matters with the filth
If you get taken to the Police station DO NOT accept the duty solicitor they will offer you and try and get hold of a known Barrister/Solicitor from your area and Keep your f*cking mouth shut until you get one.
Use legal aid or you could end up owing a fortune in court fees if it goes tits up.
And seriously don't panic because a Criminal record means f*ck all unless your 'Legally Spent' and you don't even have to declare a Criminal record on a job application etc unless you have been (Legally Spent)
It's a pretty minor offence and if it's your first then it's simply a slap on the wrist imo or if your Lucky you'll get community service (which is where you can make untold naughty contacts for the future)
