Can We Say Power Trip?

I’m still having trouble wrapping my head around the details of this Florida case. If the police tell you to stand down and you don’t, aren’t you at least guilty of something? Can’t we call it failure to comply? According to the unofficial versions of the story, the police told him to stop following the kid and stay in his car. After his conversation with the police, he continued to follow the kid and then he got out of his car and confronted the kid. I don’t understand how anyone can say that it was self-defense. This guy was clearly in the wrong. I watch enough Judge Mathis to know that.
