No.  It's been used to authenticate.  I guess your concern is a malicious
Plod trying to dupe the authenticator to give access to Alice or Bob's data
using Alice or Bob's authentication token.  But it really doesn't work like
that.

That's what paragraphs 3.14 and 3.15 are intended to convey.

They wouldn't have gone down the route you're suggesting in the first place.
And Part III is not extra-territorial, so a notice cannot be enforced
outside the UK.  They would, more than likely, engage the assistance of the
local authorities using their local legislation.

Remember that Part III requires someone to have the protected information or
be likely to obtain it.  If the protected information is outside the UK it
is, more than likely, beyond the jurisdiction of that person.

We can think about that, but anything in the code would only be indicative
rather than prescriptive.

No one is saying people can't keep secrets from the Government.  People can
keep their secrets, but if the secret is about something harmful to society,
or is believed to be something like that, we're saying that in accordance
with the law people with such secrets will have to disclose just what it is
they are keeping secret or how they keep that secret.

If my secret is abusing my niece, is that a secret I should keep from
Government?  I may want to keep that secret but should the law which seeks
to punish me for the abuse protect my secret.

You're right.  Murder and robbery, and let throw in child abuse, are crimes
and they hurt people. If the evidence of those crimes is protected should
law enforcement just walk away?  No.  If we can make it a requirement that
is used appropriately, only necessarily and never unnecessarily, only
proportionately and never unfairly or arbitrarily, and make that requirement
enforceable by law, as we do with requirements to give breath samples at the
roadside, that is surely in the best interest of the public in order to deal
with those individuals who hurt people.
