I frankly don't know a lot about the sex offender registry. I have passing knowledge of it, so I can't comment on that too much. I could find someone who is an expert in that field and have them testify here, if that is of some assistance to you.
In terms of the flagging system, the initial conception was anyone who was getting close to a dangerous or long-term offender application would be flagged. So you need a pattern of behaviour. If the pattern is just a little bit shy, as it sometimes is, and we don't have quite enough to establish the pattern, then for that person we'd gather up the information that was available at the time and put it in the flagging system. So the next time that person is arrested, regardless of where it is in Canada, whether it is in Prince Edward Island, where there are nine crowns, or in Ontario, where there are 800, the crown doing the bail hearing would within a day have all the information they could conceivably need to deal with that particular offender.
