Not as a 'victim', but I've sent a food few to court. Got one in particular locked in the chokey for nearly 2 years, which is good going by the standards of UK law.
I'm presuming it's Crown Court, as it's an indictable offence? This is good. The 'hot dogging' you see lawyers doing on telly is childish stuff that is usually confined to the magistrates courts. Judges generally don't allow it in their court rooms, so things are generally quite civilised in Crown.
You'll have the benefit if the Witness Service, who'll show you around, show you the courtroom before the day gets going, generally tell you what to expect.
As aforementioned by my esteemed colleague, Inspector Brandane of the yard, there's every chance he'll go guilty and it won't end up at a full trial. It's utterly wrong, but defence lawyers still like to test the system rather than the evidence and they may be waiting for key witnesses to drop out etc, so don't be too surprised if within a few weeks of the trial date (or even the day before, can go down to the wire) if you get stood down.
