Yes. I think that last point made by Mr. Shur is a very important one, and it means that a lot of emphasis needs to be put on the risk assessment that is made of witnesses. Do the criminals actually have the capacity to pursue these people, and therefore is some short of short-term relocation going to be sufficient in order to ensure their safety?
I suppose the other thing we've been developing in the U.K.--this has been enshrined in legislation--is all sorts of special measures that are being introduced into the courtroom in order to protect the identity of witnesses. That ranges from live television links, video recorded pre-trial cross- and re-examination, giving evidence from outside the courtroom via some live television link, using screens within the courtroom, and so on. So a lot of policy emphasis over recent years has focused on trying to make the courtroom a more secure environment within which witnesses can give evidence and their identities can remain hidden from the accused and their associates.
