Apple refused to unlock the Pensacola shooters I phone. They had a warrant. Apparently they provided "gigabytes" of info though. No backdoor to unlock the phone. I wonder why? Because they have dirt on every human that has one of their phones and only they want access to it to dispense as they see fit.
We don't know what was in the warrant. But, it's pretty simple. If they had a warrant for the residence to look for "XYZ" and "XYZ" could be contained within the safe, they can search it.
Fourth Amendment
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.
As far as the company giving out the backdoor code to get in it? They don't have too that was their choice. As far as me buying one of their safes? Never going to happen.
Stirring shit? Well, hell yeah!
