This is not new and has been lab policy for as long as I have worked in Labs.

An exact type of incident happened at a lab I worked at and it is an delicate situation for the family concerned, to say the least.
I am surprised you did not get a phone call from the Lab owner , before the film was reported, If you had a relationship with them
I think the owner may have made a mistake in not giving you a call.

But you also must know that within many Labs, the policy is there and if a technician finds work inappropriate there is this chance of reporting and the lab owner, has to comply.
This policy btw has been in place for over 30 years and I do not think it is a sign of the times.
I am speaking of policy within Canada , but I think its pretty global.
