Speaking in relation to the U.K. experience, as far as I'm aware there are no specific measures to achieve that. People are not set up with new businesses or, as far as I'm aware, even given support in terms of seeking new employment and making job applications and so on. I think there is some support in one area that has caused some difficulties in the past: when people have been moved to new communities, getting references from old employers in order to get employment has been very difficult, and I think several police forces in the U.K. have begun to find ways of helping witnesses from that point of view. They are getting references from people, but in ways that wouldn't compromise the security of witnesses.
It is very difficult, and I think certainly the U.K. evidence is that a high proportion of relocated witnesses who have had a history of being involved in criminal activity return to criminal activity within a relatively short period of time of being relocated. In a sense, they can't give up the world that they are most familiar with, and a lot of them do return to crime relatively quickly.
