"Loyalty to Jehovah can be tested when a friend gets involved in wrongdoing that needs to be
brought to the attention of the elders
Never allow misguided loyalty to a friend to overshadow your loyalty to Jehovah
Approach that friend, and urge him to report the matter to his parents or to the elders; tell him
that if he does not do so within a reasonable period of time, you will (Pr 27:5; w91 6/15 21)"
Interestingly, they stopped using the scripture they used to show to justify the "rat principle" Lev 5:1. In the 84' NT said
‘Now in case a soul+ sins in that he has heard public cursing*+ and he is a witness or he has seen it or has come to know of it, if he does not report+ it, then he must answer for his error.
By this they said that it means if whenever we get to know about a sin (heard public cursing) we should report.
However, in the 13' version this verse says:
If someone* sins because he has heard a public call to testify*+ and he is a witness or has seen or learned about it and he does not report it, then he will answer for his error.
They actually made an improvement in this translation. It's clear now that the responsability to report the sin falls only on the person requested to do it by the authority about a specific sin he/she may know.
When I saw that I said, wow, if they changed that it's signal they are willing to change the "rat policy".
As this speech shows, I was wrong. This time they just ignore the scripture they used so much just because now this scripture doesn't fit with the "truth".
