The Pennsylvania Supreme Court on Thursday waded into questions about whether the Pennsylvania Department of Transportation should be able to fire an employee who posted a Facebook rant in which she said she “will gladly smash into a school bus.”

The half-hour argument session in Carr v. PennDOT focused in large part on how the woman identified herself in the post and Facebook profile, and how those factors could play into the decades-old test used to determine if a public employee’s speech is protected.
