Lynn:  I don't 'do' FB.  That dialogue was taken out of the original story published from this rag.  That was the cops and the victim's/perp. first encounter.

It was mixed messages.  Cop wanted to ask questions.  Male didn't.  Male asked if he was being detained.  Cop said no.  Male started to leave and cop got physical because he really did want to detain this person of interest and ask questions.  

Either the cop should have accepted the male didn't want to hang around and answer questions if the cop told him he wasn't being detained.  That's our right.  Or the cop should have just stated yeah....he wanted to question the male and own it.

That, in my mind, is basic courtesy and clarity.  Two behaviors sorely needed by all of us.
