If the government wants to get in they’re going to get in. They can also hold you in contempt until you do.
Don’t get me wrong, it’s a good thing that law enforcement cant easily access this on their own. Just feels like the government is working with Apple here to help move some phones.
Anyway, it's a good thing to be skeptical about claims that iphones can't be hacked by government agencies, as long as it doesn't mean you're driven to dodgier parties (as those are guaranteed honeypots).
