out who the criminal actually is.

One of the security issues with fingerprint readers is that they still
work when you are asleep. (Not a problem if you lose your phone but can be
a problem for those in abusive relationships).

I'm not convinced that its much of a real issue.
It wouldn’t be that easy to use the finger of a
sleeping person without waking them.

If a phone was lost at the scene of a crime are law enforcement allowed to
ask suspects to just put your thumb here for a moment?

That varys with the jurisdiction.

Surely the same applies to face rec - hold the phone up to a suspects face
and job done.

Not necessarily, the best ones don’t work with closed eyes.

Bet they wished they used a PIN now.
