Could be, they may have been spoken with you about a fictive case where even the murder or raper would have been given a chance to repent in a group internal so called " judicial committee " before they report the incident to police at all or they may have thought of a case were it turns out that a person was a murder in the past and what would be done then. Lately the law office decides. It seems that cases are handled with big mery within the group sometimes, everything according to the "Sheperd the Flock" Book, where all cases and instructions are written down.
That even if 2 witnesses saw the accident it would not be reported instandly to police, shows how mislead the group members are. JW have permanent fear to do something false, even in case of witnessing crime, rape. There is a complete fear to go to the police before asking the elders, ignorance ("perhaps reporting to police is something that jehovahs displeases, then better no") what means civil courage and what are elders duties. The only thing they shall obey is that everything has to be asked the elders and reported only to the elders, who than may report to the JW-attorneys. The elders are acting according to their instruction from the law office, a private entanglement or engagment is avoided.
The JW system is self-interested and self-concentrated, the own group security is in first place, even in such cases. they protect themselves but not possible future victims in the civil society. (This is solely my private impression). Once a elder told me that in case of a thief he has reported personally to the police but that was long ago.
