It's about time somebody slammed the door on those stupid backdoor arguments once and for all.
Law enforcement has everything it needs to obtain data on someone ; it's called a subpoena and it just has to be signed by a judge who agrees with it.
You have no right to transform every petty police officer into a member of the NSA, capable of delving into people's private lives on a whim.
And, talking about the NSA, the violation of people's private lives simply because you can is disgusting.
