Re: Files are not testimony
Can a court compel you to unlock a personal safe and allow law enforcement to gather evidence from it?
No, they can't. But there is nothing stopping them from breaking into the safe (if they can) to find evidence.
This is the same situation, except the device is purely electronic. Law enforcement are free to attempt to access the device but should not be allowed (under any statutes) to compel the owner to unlock it.
