Purpose :
There was an unexpected behavior with Skyrim’s Radiant Story(a unique storytelling feature that acts as a narrator for the player) when the game was released back in 2012. The design team started getting caught for crimes more often than they should have when they were developing the game, and it wasn't immediately obvious that the chickens were ratting them out. The bug was never fixed in any of the patches that came for Skyrim, probably because it was incredibly entertaining for the players and they requested to keep the game as is. Whatever the reason was, the bug still exists in the current version of Skyrim SE. 

In 2015, Pharros created a mod called “No Animals Report Crimes” to address this issue for the chickens and lots of other factions. He also offered the mod to the Unofficial Patch Project Team who had already fixed the bug for chickens at the time and Arthmoor from their team responded that they have decided to only keep changes to the farm animal and player horse factions as they were actual bugs. The rest of them are almost certainly incapable of reporting crimes as they have received no reliable reports that can be traced back to those. With all that said, I still wanted to have this fix in my mod list to avoid that 1% chance in which other NPCs might trigger this bug so I have re-created the NARC mod with a few improvements that I explained at the bottom of this page.
  
Instructions :
The main plugin and all consistency patches are provided inside the same archive in ESPFE format.

This mod is safe to install, update and uninstall mid-game. There won't be any problems if you decided to merge all plugins together, after deactivating the unnecessary ones.
