Is it illegal for someone to falsely accuse you of you threatening them when there's absolutely no proof to back up their claim?

There are no written records, no phone calls, no email, no texts about a threat even happening. It’s all he said, she said type of thing. I’m not talking about me personally but in general.

How can someone falsely accuse you of being threatening when you did not exhibit that type of behavior at all? You were behaving in a calm manner, you were quiet and didn’t say much.

People misconstrue everything these days. They claim their life is in danger when it’s really not. Drama queens exist everywhere.
