Does privacy protections apply to those who forfeited their rights because they tried to murder someone?  

Though there is no such thing as privacy rights these days anymore, to the commoner, it may seem that way.  

 im sure it won’t set a precedent, and theyll only do it this one time.
big centralized statism is good sometimes right?

 We are all criminals 😄

 "The right of the people to be secure in their persons, houses, papers, and effects, against unreasonable searches and seizures, shall not be violated, and no Warrants shall issue, but upon probable cause, supported by Oath or affirmation, and particularly describing the place to be searched, and the persons or things to be seized."

If Prosecutors obtain a warrant for access to these papers and effects, then Apple should help execute that court order.

As much as I don't believe or trust Trump on anything, ever, in this particular case he's not wrong, as long as a warrant has been issued by a court of law.

 So, should prosecutors and this man's defense attorneys not be able to gain access to evidence that could prove his guilt or innocence? Are the to be no consequences for anyone to do anything anymore?
