You've attracted the attention of the federal side of things, sir.
Section 12403.7 of the California State Penal Code provides that controlled substances such as tear gas and pepper spray may only be used in instances of self-defense. Any other circumstances will likely be classified as assault, which is a Class-A misdemeanor in most states. As a federal officer of the law, I'm required to investigate this to the fullest extent, and this conversation will be submitted into evidence.
