"There are signs that you can look for. But be aware and don't overreact," said Downes.
Imagined Love, Real Prison Possibility
In 1990, California passed the first anti-stalking law following the 1989 slaying of actress Rebecca Schaeffer by an obsessed fan. Today, anti-stalking laws have been passed in all 50 states.
Meanwhile, Dawnette Knight's attorney has stressed that she should not be placed in the same category as Schaeffer's killer.
Knight, her attorney Richard Sherman has said, has apologized to Zeta-Jones in a letter and was never really a danger to the actress. Authorities, he said, should not have been arrested Knight but profiled her instead.
Knight faces one stalking charge and 24 felony counts of making criminal threats for acting on an imagined relationship with Douglas. If convicted, she could face a very real sentence of up to 19 years in prison.
