Parents at a school in Lindenhurst, NJ are protesting the school district's removal of security officers from its elementary schools.

Daniel Street Elementary is one of six schools that will no longer have security officers when classes resume in January. The security officers were placed there after the Sandy Hook massacre in Connecticut a year ago, said Newsday.

The district's middle school and high school, which have long had security officers, will continue to have them, Newsday said.

The security officers at elementary schools were always intended to be temporary and were not budgeted for this year, Superintendent Richard Nathan said. He said the security officers were kept on in September because the district had not finished installing panic buttons. The buttons are now in all of the schools, Newsday said.

Earlier this month, the school board approved new security measures, including additional video cameras, card access control, video intercom systems for greeters, text message one-button lockdown and door-ajar notification.
