[Black Mirror: White Christmas] Why go through all this trouble to convict a man whose mind you own.

The point of White Christmas is the police have recorded a man's mind via advanced technology, and are trying to get it confess to murder. Which is fair.

Except: why go through the whole elaborate interrogation method if you can *record people's minds*? Just check his memories and see if the murder is in there. We know it's a perfect copy, or at least they assume it is(if it wasn't, the confession's testimony would be meaningless), and this isn't like White Bear, they're not being intentionally sadistic.

So why bother? When you have conclusive evidence he did it in the form of looking in his head and checking, why do you need a confession?

There's likely limits placed on what they can and cannot do to a virtual mind. Something like the police not being able to look through yout phone if it's locked without a warrant or your consent. Probably something similar to memories where they cannot expressly search your memories for incrimination but can use a confession of your memories. It just saves them a lot of headaches and paperwork to prove the memories are genuine and unaltered if they have a confession to go along with it.
