It the big mouth Mr. O'R did this, then those obscene phone calls should have been reported to the Phone Co and police who could then have ordered taps and apart from a deep pockets law suit, this could send you know who to jail.
When I was the victim of sleezy phone calls from someone I did not know those were the steps I took..I called the police first. They came to my apt, took a report and we were getting the phone co involved to track calls (this was before caller ID days) and lucky for me the calls stopped..think the perp saw the cops...but to just go for deep pockets..I don't know,,,
Just had another thought...while not a fan of O'R...just suppose this is not a harassment case but a case of Woman Scorned....say SHE made the play had he rebuked her as only he could do..so she gets even? Maybe she has someone who is a good mimic do his voice....
