Tennessee students suspended for posting teacher's mug shot to Instagram

Three Tennessee middle school students were suspended earlier this week after posting their teacher's mug shot on Instagram, prompting one mom to ask why an adult's legal troubles put her son in hot water.

"It's public information, put it that way. You can see it on social media or you can see it in a magazine."

Shanna Richardson said her son, an eighth grade student at Highland Oaks Middle School in Memphis, was issued a three-day suspension with two other students for posting their teacher's mugshot to Instagram during class, WMC5 reported.

The teacher, identified as Tiffany Jackson, was arrested earlier for driving with a suspended license, according to the station. On Friday, a group of students posted the image and then Richardson's son re-posted it.

Richardson told the station she did not think it fair her son was disciplined for re-posting a photo that was public record.

"It's public information, put it that way. You can see it on social media or you can see it in a magazine," Richardson told the station. She said her son apologized to the teacher and deleted the post, but was still suspended.

Shelby County district officials, however, called the incident "inappropriate use of electronic media."

School spokesman Christian Ross told FoxNews.com the students were not disciplined for posting the photo and said their three-day suspension was changed to one day.

"The reason they received disciplinary action was not because they were sharing the image on social media," Ross told FoxNews.com. "The reason was because they were using district computers -- not personal cell phones -- to access inappropriate websites and content not related to the lessons that day."
