No, but without Julie's evidence, there was really only the silencer evidence. Everything else was fluff and speculation.
You see, it's this anomaly which concerns me about ANY case. A witness may be found to have said -or not said- something which leads to a convicted person being freed. However, being freed on a technicality doesn't make them innocent. When this sort of thing occurs, I start to get noble cause corruption. I must start to take my own heeding on board that we can never get anything 100% correct.
