I could have called that in a heartbeat.. NEVER open the door when he's BANGING on it...
You need to get aggressive so he can see you mean business... You threatened to call the cops and he backed off.. THAT is what you NEED to do MORE of... I would have just CALLED the cops instead of threatening...
And I would have left the facebook post up too...
Peace bond, etc... I would call the police anyways so a report is on file that he showed up trying to take the PC and threatened you...
Get it on FILE.. NOW...
Even if its late you call the cops anyways.. they record every thing... you want to have a record on file that he visited... call the cops about it... let them take your complaint down
