I really never got the, it's ok because 911 didn't specifically say cease and desist immediately, just listening to the tone of the dispatcher's voice when he said it, there's no way that he didn't know that they said it for a reason. He's the one that called 911 for help and direction, they gave him direction. Ok that's enough, let us handle this.
It's not as if they said, Oh that's so nice of you but you don't need to do that, and then he responds oh it's ok I don't mind.
And he said "OK", he knew what they meant.
Maybe he wasn't actually breaking the law but it showed his intent.
JMHO
