CHERRY HILL, N.J. — Officials in New Jersey have recommended that a high school add armed officers after a teacher was suspended for his comments on school security, including saying a Florida-type deadly shooting could possibly happen at his school.

Mayor Chuck Cahn issued a statement Tuesday on security after hundreds of Cherry Hill High School East students staged a walkout to protest action taken against teacher Timothy Locke. The walkout came one day after another student protest there.

“This is an issue that requires immediate action,” Cahn said. Cahn noted that Police Chief William Monaghan recommended police officers be stationed at district schools.

Locke was placed on administrative leave Thursday after discussing the Feb. 14 shooting at Marjory Stoneman Douglas High School in Parkland, Florida, that left 17 dead. Locke voiced concerns over school security and said a similar event could happen at the Cherry Hill school. He said the two campus police officers are not armed.

Many parents and students share Locke’s concerns and believe the teacher’s discussion was relevant. They have called for his immediate reinstatement.

School district officials have declined comment on the matter because it’s a personnel issue.
