Re: Files are not testimony
"Proving a password to view the contents of an electronic device is no different than authorities searching a residence and finding documents."
Actually, no. In the US, for authorities to search a residence or other location (there are limits), a warrant is required and it has to state what is being sought and where it is believed to be. A judge has to be convinced that there is a good chance that what the police are looking for can be found and will be at the location named. Fishing is not allowed, nor is using a search warrant for one thing allowed to find something else. The case law is endless.
Did I miss what they are hoping to find by searching the files on the phone?
Step one: Don't put anything on your phone you don't want made public.
