The atmosphere was oppressive.
Actually, a bullet is also a kind of gift, and like all gifts, it carries a message during the giving process.
Giving chocolates is like an indirect confession of love.
So giving a bullet has meaning too, and it means "you will die by a bullet," which is often used as a "death threat."
When Lance placed that bullet on the stack of bills, Officer Ferren suddenly came to his senses, greed pushed aside by reason, and he even felt a trace of horror!
"Lance..." His expression soured, "I am an officer!"
Lance shook his head slightly, "Yes, but you've overlooked a few things."
"First you are a person, then you have a family, and lastly, you are an officer."
"Are you threatening me?" Officer Ferren found it somewhat incredible, although federal police were often threatened, he still found it incredible.
Lance remained calm, showing no sign of emotional fluctuation, "You can take it as a threat or as a warning."
