I thank Dr. Willis and thank her also for the tour on the day we were with Forensic Science Ireland. My first question is in relation to the casework. It may sound so in the way I articulate the question but I do not mean this in a negative fashion: how many of the cases that FSI presented in court have been discredited or rebutted by the defence or by the other side bringing in their own expert witnesses?
