Des Moines Register
Lawyers representing Mary Beth Tinker and John Tinker, plaintiffs in a historic free-speech court case that originated in Des Moines, filed a “friend of the court” brief in support of a Pennsylvania teenager who sued after she was suspended from a public school cheerleading team in connection with a vulgar outburst on Snapchat. She argued that the Mahanoy Area School District should not be permitted to punish her for things she said outside school. The case goes before the U.S. Supreme Court at 9 a.m. Wednesday. This excerpt from the Tinkers’ brief has been edited to remove citations and footnotes and condensed.
