A chill ran up my spine after I read http://yro.slashdot.org/story/13/12/19/2113235/proposed-california-law-would-mandate-smartphone-kill-switch
Right now, as it is, NSA can listen to your telephone communication, can read your sms/email, can know where you are, who you regularly communicate with, can profile your behavior (when you will do what at where), but they still can't shut you off (unless they send in a "cleaner").
With the Kill Switch, they can do that.
Yes, the law as it is, is for people who report to the police that their smartphones were stolen, so that the authority can issue a "kill order" to brick that lost smartphone.
And we also know what NSA is all about - no law on the land can touch them - and with the availability of the "Kill Switch", NSA can effectively KILL THE PHONES of those who they do not like, cutting them off the communication grid, and leaving them out in the cold.
I can foresee the consequential abuses that will accompany this new "Kill Switch" law. It'll only make NSA (and all the other BIG BROTHERS) that much stronger.
