So if you don't unlock your phone, it's an admission of guilt.

I understand the evidence indicates that some people do choose not to unlock their phones on demand by police, even when they are innocent. You can interpret that as an admission of guilt if you like; this puts you in the same moral boat as police who write up a confession for someone and then fake their signature, because they just know the guy is guilty.

You can say what you think all you like, but the evidence is against you.
