Hi Stickle can I just say that you should get in contact with the Witness service at the Crown court and arrange a pre trial visit, so that your son can have a look around the building, know where he will be able to wait safely prior to giving evidence what the procedure will be etc, A lot of people find this extremely helpful, (you probably will too) but just remember Witness service are impartial and will not be able to talk to you about the case itself and if you have any questions about the case itself you should speak to the officer in the case ..
