These things should be simple:

1. When, as an adult, you come come across another adult raping a small child, you should a) do everything in your power to rescue that child from the rapist, b) call the police the moment it is practicable.

2. If your adult son calls you to tell you that he just saw another adult raping a small child, but then left that small child with the rapist, and then asks you what he should do, you should a) tell him to get off the phone with you and call the police immediately, b) call the police yourself and make a report, c) at the appropriate time in the future ask your adult son why the fuck he did not try to save that kid.
