In Person of interest episode S01E19, it is seen that Elias' men are following the families of police people of the HR group. It is suggested that they will threaten the families if they will not work for Elias.
Finch talks to officer Simmons that he the HR group should leave everything alone and not support Elias. In view of the threat (Finch also shows Simmons photos from it!), this makes no sense to me. If I was Elias, I would gave the order to do something with the families as soon as Elias gets arrested, killed or is missing.
Can someone explain to me what was the reason the HR group did not support Elias anymore and why was there no immediate counterstrike by Elias' men against the police people's families?
