Thanks very much.
I want to pick up where my friend left off, on the standard. Obviously you've received information or have requested information under SCISA already. Can you give me an example in which information you have received was useful and added value, but wasn't necessary?
I still want to get at why we can't have a necessity standard. I get that Global Affairs might have a hard time doing it, but if the Privacy Commissioner is saying it, if the academic experts that we've heard have all said we should have a necessity standard, give me a specific example showing why a necessity standard would impede your investigations.
