If you witness child abuse and say nothing, you bear some responsibility for its continuation.

This is a broken system. When somebody allegedly steals a backpack they get thrown in Riker's. When somebody with substantial power causes a whole bunch of people to die in aggregate via pollution, misinformation, or whatever our society has no mechanism to punish them.
That would be an extraordinary claim.
