A teacher at a Long Island high school presented a slideshow that included a photo of four black students at the Bronx Zoo with the caption “Monkey Do” followed by a snap of a gorilla — and now the students and their parents served a notice of claim Wednesday that they’re planning to slap the school with a lawsuit.

The photo of the Longwood High School students — which was taken during a class field trip to the zoo on Nov. 5 – shows youngsters lined up behind one another with a hand on the person’s head in front of them.

“One person said that they look like slaves,” Latisha Moye, a mother of a 16-year-old boy in the snap told News 12 Long Island.

Moye added that the “whole picture and the caption was very upsetting because it was comparing our kids to a monkey or a gorilla, which, there is a history on this when it comes to black people — so it was very disturbing.”

Lawyer John Ray, who is representing three of the students and plans on suing the school for $12 million, claims that the Suffolk County school “allowed white teachers” to label the students as “monkeys” in what he said was a “school-sponsored zoology class slideshow” that was made before winter recess.

Ray called the slideshow “grossly racist” and said that it “compared” the black students involved “with slides of monkeys and a gorilla.”

According to the notice of claim, school employees, including a zoology teacher, identified only as Mr. Heinrichs, “created and manipulated” the photo so that it was placed in a slideshow between a photo of monkeys with the caption, “Monkey See,” and a picture of a gorilla “thereby misusing the pidgin expression, ‘Monkey See, Monkey Do’ for racially discriminatory and offensive purposes.”

The slideshow was then given to another zoology teacher at the Suffolk County school and it was shown to students on Dec. 20, “holding claimant students up to ridicule, embarrassment and shame, anxiety, fear and emotional harm,” the legal document says.

One of the students in the photo was taken by school authorities to the school’s administrative offices that day where administrators “pressured and threatened to suspend said claimant if said claimant failed or refused to destroy his evidence of the slideshow,” according to the notice of claim.

The document says that the actions of the school officials “were unlawfully discriminatory” and a violation of the students’ civil rights.

In a statement, the Longwood Central School District admitted that the photo was “culturally insensitive” and that it was “an unfortunate lapse of judgment.”

“Without the intent of doing so, the photo was taken without fully understanding the sensitivity or the hurt it may have caused and reminds us that we must be more aware of the feelings of our multi-cultural population.”

The district said that since returning from winter break, the Superintendent and the High School Administration has met with the teacher, community members and the families involved.

“We are proud of the diversity at Longwood Schools, and we will continue to provide sensitivity training to our students and staff to raise awareness of our cultural differences,” the district said. “Longwood is committed to providing an educational environment that is nurturing, supportive, safe, and conducive to learning.”

The school district would not say what, if any, disciplinary measures were taken against the teachers involved, and said that “due to pending litigation” it has no further comment on the matter.

But the students’ attorney claimed that the teachers involved are still teaching.
