The NAACP is backing the three teens charged in an altercation at Lincoln High School that left a campus police officer severely injured.
The organization called for charges against the accused students to be dropped until surveillance video of the Feb. 22 on-campus incident is released.
Andre Branch, president of the San Diego chapter of the NAACP, said, "The charges need to be dropped because a proper investigation did not happen."
Branch said of the surveillance video: "That's a public document; it's a problem when everybody is denying the public an opportunity to view it."
Branch claims the injured officer has a history of provoking confrontation and overreacting, adding the officer is responsible for two of the four stun gun-related incidents in the San Diego Unified School District since 2009.
The San Diego County District Attorney's Office says the officer was seriously injured in an attack started by a 17-year-old student -- a star for the school's basketball team. Investigators said the teen jumped the officer from behind, stealing his keys and radio before two other students joined in.
The officer managed to deploy his stun gun on one of the teens amid the chaos, investigators said.
Branch asked for a permanent end to armed officers at Lincoln High.
"Their presence sends a clear message that our students are dangerous … There are not armed, uniformed officers at schools in Clairemont, in La Jolla, at Scripps Ranch …," said Branch.
A district spokeswoman told 10News an armed officer is present at all district schools.
District officials said: "The Lincoln High School community has demonstrated real character in how they have come together following this incident. We will continue to support the school, our staff and students as they continue the healing process."
