PLAINVIEW, TX -- A Texas mother wants to know why the assistant principal of her son's school drew on the boy's head with a marker, KCBD-TV reports The mom claims the school believed her son had a "gang-related" haircut.Monica Esquivel is upset and wants the school administrators to apologize to her son Kobi.She says that administrators told her that this type of haircut could be considered gang-related. But Esquivel said she does not raise her son to portray that type of image."My son is not in a gang, he's not trying to be in a gang. I mean, he dresses in khakis, a shirt, not in loose pants or nothing, just real nice and casual, not representing a gang or anything," she said.The Plainview, Texas, school district's executive director for administrative services, Greg Brown, did not deny that the incident happened, but says he cannot comment due to confidentiality. But he did release a statement saying that the dress code, "prohibits designs shaved into the scalp, and this includes lines."A copy of the student handbook outlines that no designs are permitted, but it also states it's not an all-inclusive list. Esquivel says that she has repeatedly told the school's administration and strongly believes that Kobi's haircut does comply with the dress code."And when I got copies of the dress code, on there it says, designs shaved through the head, but I said it's not a design, it's the haircut. The style that's coming out is the comb over," Esquivel said.The dress code, Esquivel says, should be updated."They're expecting, you know, the kids, they get distracted on stuff, but it's starting to become where everything is a distraction to them," she said.
