If you made it known that you were prepared to hear testimony on this, I think you would get a wide range of individuals and groups that would want to come forward and make their case one way or the other.
As Mr. Siksay pointed out, I've had a look at this whole issue, I think about 20 years ago, and again, you get some good insight into the different issues. I think it could be very helpful and very instructive for the committee, and indeed for those of us who work on these issues.
