The city has the fewest number of predators per capita in Alameda County, while other cities of similar size can number theirs in the hundreds.
"There isn't a really big problem here," Alameda County sheriff's Deputy David Kozicki told a handful of people at the forum, held on a Wednesday evening at the Amador Valley High theater. "In Pleasanton, there are only 34."
Kozicki said there are about 2,900 sexual predators in the county, and approximately 88,000 in the state.
Police actually have two lists, one for the public, viewable in the Megan's Law database, and a separate one for their viewing only.
Of those in Pleasanton, 28 are viewable on the Megan's Law website, and four are for police eyes only.
All of them are required to register with the Pleasanton Police Department when they move to the city and required to re-register within five days of their birthday every year.
"There's nobody that we know for sure that's in violation in Pleasanton," Kozicki said.
Failure to register or to renew their registration comes with some harsh penalties, he said. A first-time failure is a misdemeanor, carrying sentences of 16 months to two years in jail, and by law, the minimum amount they can spend behind bars is 90 days.
"That's just for not coming in within five days of your birthday," Kozicki told the small group.
Experts say sexual predators "are not rehabilitatable," he said, and they're required to be checked by the police department, including submitting to lie detector tests, and to undergo regular psychiatric exams.
Kozicki said while most families fear for their daughters and warn about "stranger danger," most sexual predators are known by the families of their victims, and most target boys.
But just because the city doesn't have a large population of registered sexual offenders doesn't mean people should relax, Pleasanton Community Services Officer Shannon Revel-Whitaker told the group.
"We have people in society who haven't been caught yet," Revel-Whitaker said, advising people to trust their instincts and ask questions if they have concerns.
