It's absolutely critical in judicial authorization, but we could also imagine circumstances where exigencies would exist. The example that is being used perpetually now is the idea of being able to say to somebody's parents that their son or daughter has been radicalized and make them aware of it and whether or not that would be an example of disruption. We could think of far more serious cases where disruption might be necessary, and we'd certainly want to see judicial authorization for those kinds of instances to the extent that it was possible.
