"I think if we were actually serious about victims, instead of using that warrant for a Kill Switch, we'd use it to query the networks and track the breadcrumbs"
I don't know that I'd object to that. I'd still demand an owner-provided code. Note that I've never been saying "this system is amazing and exactly what we want", I've been saying "there is a legitimate up-side" - which I stand by, and which the existence of better alternatives don't undermine.
