In the next few days, Luke and Selina basically used the same trick to scare off many "chat groups."
One word: Bluff!
They wouldn't arrest them; Luke couldn't be bothered to arrest these sorts of brats.
But they also couldn't not do anything. Otherwise, if multiple brawls or even gunfights broke out, that might cause a chain reaction.
Soon, it was 10pm. Luke and Selina had completed their "voluntary 2-hour overtime" for the night.
Selina had already reported to the main desk. Once their shift was over, Ricky and Kajit, two colleagues from the Organized Crime Investigation Bureau, would take over.
They were closer to these two colleagues than to the patrol officers.
At the very least, the Detective Bureau and the Organized Crime Investigation Bureau could be considered "departments" under NYPD HQ, and had worked cases together for a long time.
