GO TO THE POLICE.

Their hands are tied anyway. The police can't do anything until somebody can PROVE a law has been broken, which is often way too late. Let them know you're being harassed (which is illegal, by the way) and have them refer you to an advocate who can explain to you how to document the harassment.

This is a police matter. You are not required to tell him that you've gone to the police, and it's often inadvisable anyway, as it can send a stalker into a rage. If they don't want to be bothered, insist that they tell you who DOES want to be bothered with crime PREVENTION, whether it's a city office, local nonprofit, or national coalition, so you can get some backup from people who are experienced and know exactly how the law can and can't serve you.
