These provisions are so intrusive that I'm concerned about the relationship they could create between the government, security agencies, and the community itself. It's so pernicious in its potential impact that I think you have to reserve it for the most extreme circumstances.
When you have time, you use all the tools that are available to you. I know I'm speaking on behalf of an Islamic organization, but these provisions, the investigative hearings, are a Hail Mary pass, to use a Catholic expression. In security terms, it's a Hail Mary pass. You believe something is going to happen and you have no idea of where it's going to come or how it's going to happen, but you have an idea that a group is involved, so you grab a person who belongs to that group.
