Obviously in a program like this, except for the cases that Mr. Swadron has often defended, concerning perfectly innocent witnesses—I understand that you are talking about people who, over the course of their lives, were witnesses to major crimes, and their testimony was important, but if they are known, they could be threatened or even eliminated. Is that what you are talking about when you refer to totally innocent witnesses?
In most cases—and in the United States, I believe, it is 95% of cases—they are people who have engaged in criminal activities, whose testimony is needed to convict other people who participated in those criminal activities. Those people are risking their lives by cooperating with the police. That is why a witness protection program was created.
I would mention in passing that I started practising criminal law in 1966. At that time, there were no such programs. It seems to me that in all civilized countries that have legal systems comparable to ours, and as reliable as ours, these programs have been created. I was there when they were created. It was done on a bit of an ad hoc basis at first, before there was a law.
One of the things that concerns us is that these people were offenders and are at risk of offending again. When we sign an agreement with them to protect them, we think that there is no danger of them committing further criminal offences in the immediate future. They are well aware that if they commit another criminal offence they will lose the protection they enjoy.
We are even prepared to give them psychological support. After a certain time, however, if they have not committed any criminal offences, we abandon them completely.
You have a practice in this field. Do you believe, in practice, that it would be wise to do regular supervision or regular psychological evaluations?
Obviously, it is very difficult to do a psychological evaluation of someone's tendency to commit crimes, and I recognize that. On the other hand, we do monitor people on parole, where the officer assesses whether the release is a success or not.
Do you have any opinions about the kind of measures we should take to try to prevent these people from committing serious crimes? What prompted us to study the question were cases in which some of these witnesses had subsequently committed murders.
Do you have an opinion about the psychological support or supervision there should be while they are in protection?
