Mr. Speaker, the hon. member brings a great deal of legal knowledge and deep thinking to all of the debates in the House that he takes part in.
In terms of preventative arrests, there are other cases where that can take place, for example under section 810 of the Criminal Code, if someone is threatening domestic violence or sexual aggression.
There was a court case recently, which I mentioned in my speech, Regina v. Hall, where the issue of preventative arrest was brought up in the context of a bail hearing. My understanding is that Bill S-7 responds somewhat to some of the points made in that judgment. However, that judgment upheld the notion of preventative arrest in certain cases.
