The comment is unclear... Does the person mean that the elders would hide the alleged sexual predator or the police officers, saying that there is an emergency? I find the latter unlikely and strange, but at the same time, the author uses the plural pronoun "them" which would indicate that s/he is referring to the police officers... But if the comment is actually talking about hiding the police officers, then it's probably sarcasm...
Having said that, I think it may be probable that some elders would attempt to hide the alleged perpetrator. After watching the ARC, I came to the conclusion that those JW elders are extremely stupid. It's physically impossible for their brains to process information on their own. One elder testified to the Commission that he would first contact the branch―instead of the police―even in a case where a member of the congregation were to murder another person. Surprisingly, that answer did not change even when the elder was asked about this member killing a second human being.
Some people are just too far gone...
