In the ongoing battle against online sexual predators, one Nassau lawmaker has proposed a measure that would enable law enforcement members and prosecutors to track predators' Internet activity.

Leg. David Mejias (D-North Massapequa) introduced the bill, which could be presented for a vote as early as November 7.

"This new legislation would require anyone convicted of a sex crime, regardless of risk level or whether or not it's a registerable [sic] sex crime, to have software installed on their computer," Mejias said.

Police, probation departments and district attorney's offices would have access to the Internet activity-tracking program. Convicted offenders would also be required to register screen names, e-mail addresses, passwords and IP addresses with authorities.

The legislation would take effect four months after its passage.

Parents for Meghan's Law Executive Director Laura Ahearn supports the proposal.

"Sexual predators are really good at what they do," Ahearn said. "We have to be one step ahead of the sexual predators. You know the extent that they will go to access sexual victims."

Mejias added that the proposal would not replace the need for parental supervision of their children's online usage.
