THOUSAND OAKS (CBSLA.com) — A viral video depicting teens screaming racial slurs is prompting parents to issue a call for action.

In the 38-second video posted on Twitter and other social media outlets, at least four teens are inside a moving car. With rap music in the background, you can hear some of them yelling the N-word and expletives targeting African-Americans. At one point, someone on the video says, “Kill black people.”

Parents at Thousand Oaks High reacted to the video and were disappointed to learn one of the teens involved is a student at their school.

“I think they should be expelled. As a joke, do you find that funny? I don’t find that funny. I find it very racist and I find it very offensive,” Jan Cooper said.

Parent Hector Allois was more forgiving.

“They’re all good kids out here … they’re constantly doing sports, they play together a lot and it’s just that somebody made a mistake,” he said.

A Twitter post said one of the teens is a Westlake High student. The principal did not confirm that but said they’re investigating.

The Conejo Valley Unified School District said in a statement: “The language and opinions expressed in the rap song that recently surfaced in a video online are not representative of the District, the Governing Board, or District staff … When a student violates district policy, we respond promptly and appropriately according to our policies and procedures.”

“Disciplined, yes, they should be disciplined for sure, but my opinion, again, all this stuff starts at home with the parents,” Allois said.

“The kids should be accountable and the parents should be accountable,” Cooper said.
