Theft by Employee at Crown Court?

I'm concerned that your solicitor is so negative about your prospects of success. Just hang on to the fact that if you didn't do this, then you shouldn't be convicted of theft. It remains the case that the prosecution have to convince the jury beyond all reasonable doubt that you did do it. Try to remain calm and think of anything you can possibly say which would support your protestations of innocence. Theft from an employer is a serious matter -- but they still have to prove you did it. Keep on fighting!
