PUDDLE OF MUDD singer WES SCANTLIN was arrested Tuesday for throwing a drunken tantrum on a flight, which forced the plane to make an emergency landing.

--Now, we have his mugshot, and a video of his arrest.

It's interesting that Wes says the backpack he had wasn't his, but was "a gift."  You have to wonder if it may have had something inside that he wasn't supposed to have.  Otherwise, why say that?
