I do, but I'm generally opposed to the use of technology where people want to have trials and have witnesses attend by teleconference or telelink. I'm often in opposition to such a method, because for me a criminal trial is a slow and deliberative process where I believe it's important for jurors, for example, to have a real feeling and appreciation for what a witness is testifying to. I respectfully feel that the ability to assess the witness is just better in person, in the flesh, viva voce, as opposed to by video link.
Perhaps I'm a relic of a bygone era, but it's just my personal preference for witnesses to be there in person.
