I can speak to criminal records in other contexts. I've been looking at how the Bedford case has been applying. There was an indigenous women who was caught up by the criminal justice system. They were looking at her record, and they said.... I think there might have been more than 20 convictions for soliciting for the purposes of prostitution and failing to appear.
I think that goes to show that these things stay for a long period of time, regardless. It could be from the seventies.
