I was speaking about preventive detention. On investigative hearings, I don't have any difficulty with the idea of narrowing its scope. My understanding of the committee proceedings in the review of the Anti-terrorism Act was that they wanted it to be used prospectively rather than retrospectively; that is, they wanted it focused on upcoming events as opposed to being used as a tool to investigate what happened in the past.
I see some sense to that, in the sense that it is an extraordinary provision for retrospective investigations when conventional criminal investigation tools are available to you. Given the possible outcomes of mass-casualty terrorism events, prospective investigations seem to be the only type of circumstance in which the extraordinary powers of investigative hearings might be reasonable. I don't have any difficulty with that idea.
