Eighth grade teacher Tiffany Jackson was arrested by police for driving while her licence was suspended. Students at the Memphis school where she teaches were suspended after sharing this mugshot online . Parent Shanna Richardson told WMC Action News said her son, who re-posted the picture, was one of the pupils taken out of school for sharing the mugshot. School officials justified suspended the students by saying they had demonstrated an 'inappropriate use of electronic media', but later overturned the decision. Ms Richardson said her son had apologised to the teacher and she thought it was unfair that he had been singled out. 'My son went to her and talked to her to make her feel better, and explained how he deleted it," she said. 'He still got punished and that's what makes me upset.' 'It's public information, put it that way. You can see it on social media or you can see it in a magazine,' she added. Officials at Highland Oaks Middle School in Memphis, Tennessee, said the children had demonstrated an 'inappropriate use of electronic media'. but later overturned the suspensions following a backlash . On the 'Cell Phone Policy' listed on the school's website and written by the Shelby County Board of Education, it says the increased use of mobile phones is a 'distraction' to the school environment. It adds: 'These devices are being used by students as a means of cheating on tests, taking inappropriate pictures and video of students and staff for sharing and posting across the internet, threatening and/or bullying other students, and engaging in an excessive amount of social interaction during instructional time.' The policy bans pupils from having a mobile phone on during the school day, and says children who flout the rules will have the devices confiscated. 'Additional consequence' - such as suspension - could follow. It is not known whether the pupils were using their mobile phones in school to post the images. The 'cell phone policy' says the increased use of mobile phones in schools is a 'distraction' to teaching, and could be used to 'take inappropriate pictures and video of students and staff for sharing.. across the internet'
