They can’t have a go at you without charging you with something first.. then you’d get a trial date all of your own… might be able to question your credibility as a witness but it sounds like you did what most people would have done anyway… have worked with the old bill I can honestly say I’ll be surprised if the trial goes ahead on the first stated date if at all (the press for a guilty plea right to the last minute to save court time) and as Davey said it’s days of pissing about for the best part of a couple of minutes giving evidence.
