What are the poster's legal options? Should the police be notified?
No. Why? Actually, I would like for the poster to try and make good on his laughable, empty threats. Were he not the cowardly turdbrain he is, I'd love for him to come about. That way I could grab him by his scrawny neck, bash his head against the wall, twist his arms so hard he couldn't jerk off for, like, forever and stomp on his minuscule testicles with my boots. And then I would shit on his face.
