As long as we have no access to the phone who knows what's on it? Let's be honest most people are not criminal masterminds. He might even have a selfie with the dead body.
If someone confesses to crime A because they find evidence of crime B, then he's really really dumb. And if they find evidence of wrongdoing, why shouldn't he be punished for that? After all Al Capone was also done in for tax evasion as well.
Then why do you have a problem with "court order, go to apple, samsung, whatever and get access to their phone"?
There is nothing special about it, it's just another avenue worth pursuing when looking for evidence.
I'm sure they'd get a court order for every person on the spot. Oh wait, it's a completely different thing. Let me refer you to #10 on the regressive agenda.
You entirely missed his point. Its not the court order to access the device we are in objection to. Its to requiring a skeleton key to every lock and giving the governments of the world that key and making them promise to never use it except when they really need to. Its like putting a kid in a candy store and telling the kid not to eat any candy and then walking out and leaving the kid alone and unsupervised. Candy will get eaten.
