Think like a sysadmin in a big corporation. Assume that there are devices (the BYOD trend) that you have no root to/ no way to monitor them. It will drive you crazy if you have a mild case of ODC(and in IT it comes with the profession) no matter what the real risk is. Now you are in FBI shoes.

With the devices so closely integrated into the cloud we are already close to the "day every iDevice was wiped irreversibly and huge part of the world stopped". Let's not make it closer.
