If she posted to Facebook from school/school computer, she might be liable.
If she posted to Facebook from elsewhere, she call tell them to suck eggs, and sue them for wrongful termination.
Is there a way to know which computer the pic came from? I’m sure that I heard someone at Sheriff Joe’s BC presser say that they could tell which computer in the White Crib created and put up the phony BC. Do computers leave electronic footprints?
Maybe not. If my employer came across any posts on Facebook or another forum (even if posted from my own home) that: (1) was obviously posted under my own name and identity, and (2) cast a bad impression on my company among people who know me as an employee of the firm ... then they would have every right to fire me.
She probably took the picture and posted to FB with her Iphone. Computers are so 20th century.
