Mr. Speaker, that is a very important point and a good point.
We know that the bill back in May 2005 did extend the retroactive scheme to cover persons convicted of one murder, one manslaughter, or one sexual assault, which prior to that was not included. Those were included in that.
I stand to be corrected here but it is my understanding that the only substantive amendment in respect of retroactive changes to allow the authorities to take DNA samples deals with attempted murder and conspiracy to commit murder. They are very serious offences.
I am not certain of the number of persons presently incarcerated. I do not anticipate it being a very large number given, generally speaking, the murder rates in Canada.
