I'm gonna go ahead and claim that laws that incur a penalty for not reporting a crime, are not commensurate with legal obligation. Such a charge sounds like a plea bargain or additional-charges or inconvenience-a-witness tool, than a legal concern. The charges for failing to report a crime are subject to prosecution that includes due process (proof, legal prosecution, etc). It's nearly impossible to prove that you witnesses a crime you didn't report without some paper/video/interview trail. This is partly why you never talk to police without a lawyer, as it can get you caught up in such a charge by your own statements.

Telecom workers with privileged access are instructed not to report crimes they overhear.

The training materials are approved by the federal government.

It’s technically a crime for them to repeat what they hear, including to law enforcement.

Some narrow exceptions apply, such as when the telecom company is committing a crime.

But technicians who have to listen in on calls (I don’t know if this is a thing anymore), are instructed to never report crimes they overhear.
