FLOSSMOOR, Ill. (WLS) -- Students walked out of class at Homewood Flossmoor High School Tuesday after a social media post showing students in blackface has sparked outrage.Around noon, about 1,000 kids spilled onto Kedzie Avenue demanding justice as they squeezed around police officers who were supposed to keep the students from leaving school grounds."It's quite a big turnout," said Kaila Chambliss. "I'm very happy with the results because this is something that systematically is happening in America now and we need to see change take place."Students staged the protest after four sophomore boys posted a picture of themselves wearing blackface on social media. Their post also included a video of one of the teens making disparaging remarks about African American women. The behavior took place over the weekend, off school property."The administration is honestly making it to be not a big thing and it really is," student Karina Duncan said.While privacy laws prohibit the school from discussing punishment, students of all races are convinced not enough is being done to the teens involved and not enough instruction on black history."All our history classes we learn about wars, fights all these other things, but we never get deep into black history," student Colin Gates said."I think they should put that in the curriculum of having an African American history class," another student, Jack Schmiz, echoed.While the walkout out lasted several minutes, most students returned to class. A few dozen stayed out and formed a circle at the intersection of Kedzie and Flossmoor.The administration has sent out several letters to parents and students, in as well as a videotape message from the superintendent and principal."We want you to know what happened this weekend is taking very seriously by the administration," Dr. Jerry Lee Anderson said in the message.School administrators met with the students involved and their parents. ABC7 has been told the incident happened outside of the school, and will not be tolerated by school leaders. The school did not say how or if the students were punished.For Janet Lawrence, who not only went to this high school herself, but her children and grandchildren too, she hopes the action of some doesn't speak for all."I've never seen anything like this before in our community, so I don't know, these are a couple of kids, I don't know who they are," she said. "They are not responsible for the rest of us. They are only responsible for themselves."READ: Board of Education letterREAD: Letter to parents, 4/28/19READ: Letter to parents, 4/30/19In a letter to parents, Homewood-Flossmoor High School's principal and superintendent said access to the campus will be closed during the walkout.The letter said,In a joint statement, Homewood Mayor Rich Hofeld and Flossmoor Mayor Paul Braun said:
