Via The Gainesville Sun:
...Murphy consented to a search of his vehicle, where officers found a “non-labeled prescription bottle containing 11 individual pills later identified as Viagra.” Murphy could not provide a prescription for it and allegedly told the officer that he had peeled the label off of the bottle “because he did not want his girlfriend to know he had a prescription for it.”
Welp. That cat's out of the bag.
What's interesting to note is the news report of the incident. There's no indication in the story whether the arresting officers told Murphy why he was being stopped. That could explain why the receiver was unwilling to provide ID. Perhaps the reason was explained, in which case leaving that info out of the story was a confusing oversight. But if Murphy really didn't know why he was being stopped, there could be something else going on.
