"
Kentucky teenager Paula Asher had one too many that fateful night she decided to drive, and she sideswiped another car as a result. Though there were four people in the car hit, thankfully no one was hurt. Asher was cited by police for driving under the influence.
The 18-year-old laughed about driving drunk on her Facebook page after the fact, posting a status update reading, "My dumbass got a DUI and hit a car LOL." The judge presiding over Asher's case found little humor in a crime that results in, according to the National Highway Traffic Safety Administration, 28 deaths each and every day. Asher was ordered to shut down her Facebook page as a result, and when she refused, the judge held her in contempt of court and had her thrown in jail for two days."
Judges have discretion to make certain bail conditions. Although, I have never heard of a judge ordering someone to take down a facebook page, as that has constitutional first amendment concerns.
