I'm not sure how it can be a crime to re-post a photo of an officer that the
officer posted online himself. It might be a different argument if the
officer was making a reasonable effort to keep his undercover work secret,
but as the article says, he was testifying in open court about his
"Mesquite police arrested Melissa Walthall, 30, for allegedly posting the
photo of the officer, who authorities say recently testified in a drug case
against her friend. Her Facebook post identified the person as an undercover
officer, according to a federal affidavit."
This doesn't sound like a crime to me. This sounds more like sour grapes.
I hope she has hired a good attorney.
