Politicians have a knack for taking on problems that aren’t really problems, proposing solutions that won’t really do anything and then exaggerating the significance of what they’ve just done.

The latest Inland politician to do this is Sen. Connie Leyva, D-Chino, who has introduced the “Keep Kids Safe at School Act,” touted by Leyva and her staff as “important legislation to protect school children from dangerous sex offenders.”

In brief, Leyva’s legislation calls for prohibiting registered sex offenders from entering school campuses. This certainly sounds important until you realize it isn’t and that it probably won’t protect a single child from dangerous sex offenders anymore than current laws already do.

To begin with, it is already a misdemeanor under state law for registered sex offenders to enter school grounds without lawful business and written permission from the school’s principal (or equivalent). Those who have committed offenses against minors age 16 and under are also barred from working or volunteering directly and unaccompanied with minors.

Under an awkwardly worded 2013 state law, registered sex offenders unrelated to any pupil at a school can theoretically volunteer on school grounds if they receive permission from the principal and all parents are notified of their potential presence 14 days in advance.

This 2013 law came under scrutiny in the Fontana Unified School District in September when the school board sought to integrate it into district policy, mostly as a formality.

Social media promptly went ablaze with hysteria, leading many to believe the district was actively encouraging sex offenders to show up on school campuses and would let them volunteer without a problem.

This wasn’t true, of course, but the frenzy prompted the board to vote against incorporating the state law into their policies and instead they passed their own rule banning registered sex offenders from their campuses, prompting a lawsuit.

Leyva wants to strike language allowing registered sex offenders on school campuses, even if they have a lawful reason to be there.

“I am proud to stand with concerned parents and community leaders in Fontana and across California to ensure that registered sex offenders do not roam school classrooms, halls and playgrounds,” she said.

If we are to take Leyva’s version of reality at face value, why would any parent send their child to school? Fortunately, dangerous sex offenders aren’t free to roam the halls and playgrounds of schools — there are already laws to prevent that.

The reason no one has really noticed the 2013 law is because registered sex offenders are unlikely to go out of their way to apply to volunteer at a K-12 school under the conditions presented, and school officials are even less likely to grant permission and go through the process of notifying each parent of their decision to allow a registered sex offender on campus.

It’s worth noting not all registered sex offenders are dangerous, pedophiles or dangerous pedophiles.

Public urinators and teen sexters are among those on the registry, and may be crime-free for years, even decades, but still remain on the registry.

California is one of the few states that require lifetime registration for sex offenses.

If anything, teachers and other school staff pose bigger threats to students on campuses than registered sex offenders.

In 2014, the California Commission on Teacher Credentialing opened 328 investigations for sex crimes against children.

Of course, teachers have strong unions by their side. Registered sex offenders don’t.
