The clerk didn’t force the police to put the guy in handcuffs. She simply said what she saw. It’s up to the police to sort out reports like that and separate fact from fiction. There’s no indication that the clerk lied or made the call in bad faith. She was genuinely concerned, and I don’t blame her, so she called the police. There’s no crime in that. The police are the ones who decided to cuff the guy.
Oh, there you go, being all logical about this.
