Yes, I know. But in fact what happens is the first time, frankly, you destroy something, someone comes along and says, “Why did you destroy it? We wanted to review it to ensure that you collected it properly.” So there is again that balance, and we're subject to the archives act, and all of those kinds of things.
In terms of communications that we intercept pursuant to warrants, we debrief them, put in operational reports, and then the tapes are destroyed after a certain length of time. And that length of time varies according to the investigation.
