In Death Note, L had the police announce that they sent thousands of FBI agents into Japan to find Kira, and show it on TV when they knew Yagami Light was watching. There were no such thing as thousands of FBI agents, it was a bluff, and Yagami Light also predicted it and remained calm. This could be a similar bluff.

(Note: This is not to compare Yagami Light to the NYC John Wick, Yamami Light has (arguably) way more unethical acts than our NYC John Wick.)
