Smartphone industry commits to antitheft measures amid calls for 'kill switch'

1) It can only be initiated by the owner of the phone, there should never be any means by which a government official can get the legal authority to kill a device. Yeah I know, but what about bombs?

2) It must be able to be overridden by entering a code on the device. As in, if the kill order is submitted the device alerts and gives a short time to enter the pass code. This prevents the possibility of rule #1 being violated now or at a later date.
