I think Mr. Barrette's example is extremely important, because it gives an illustration of how, without officially using the investigative hearing powers, you can use them as a threat over people who are not willing to be sufficiently forthcoming to a CSIS officer. The problem with this is that it alienates the community from its security forces.
To take the example that Mr. Lobb put forward, the information we have is that the bomber in Sweden was flagged by members of his own community in Britain. Had there perhaps been more competent or more effective communication among the security forces, the flagging in Britain should have carried over to Sweden. I think that's where the issue is.
I think the real lesson in all of this is that you need to protect and nurture positive relationships among the various communities in our society.
