This episode involves Briscoe and Curtis answering a call of a woman being thrown down a flight of stairs in her apartment building. Susan Floyd says she's been systematically stalked and terrorized by a man who seems to know everything about her and signs his e-mails Giovanni.
'Giovanni' is played by Stephen Gavedon and the only real connection that the detectives can establish is Gavedon like opera and his favorite is Mozart's Don Giovanni. It looks like Floyd might have faked the attack because no one was taking her cries for help seriously.
It all leads to a crisis of conscience for Jerry Orbach and a split from Benjamin Bratt. I agree with the other reviewer that Rey Curtis can sometimes be insufferably self righteous.
What I liked best though was the place where Gavedon honed his cyber stalking skills. None other than jail, a private prison run at a profit in Pennsylvania. The authorities there have their inmates working as telemarketers and of course once you buy via a credit card all kinds of information opens up on people. Score one for the free enterprise system. In fact the whole idea behind these places is to have more convicts that the state can't handle. Hence in New York the opposition to repealing the Rockefeller Drug Laws.
Good episode, I only wish there was an episode devoted strictly to that issue.
