BETHPAGE, N.Y. (CBSNewYork) – In Bethpage, Long Island Tuesday, a group of librarians attended a seminar on active shooters, held by the Nassau County police.

Chief Steven Skrinicki said the seminar helps groups know how protect themselves if a person with a gun enters their building.

“Talking about how a library can best protect itself. We are going over plans for libraries. So this is an organization that felt possibly under-prepared,” he told WCBS 880 reporter Sophia Hall.

The chief said he hopes other groups, including those in hospitals, malls, major businesses, and movie theaters will attend the seminars.

He said if you know someone who is acting suspicious, “not to be afraid to come forward and tell somebody.”

You can anonymously call the police.

“We have over 20 cases and in some of those cases, arrests have been made because there have been threats, terrorist-type threats,” Steven said. “In other cases, we’ve just referred that individual to for some psychological counseling.”

This program has been in place for over a year.
