Charges Dropped Against Puddle of Mudd Singer

TMZ broke the story ... Scantlin was arrested in Austin, TX back in September, after he allegedly got into a booze-fueled argument with a flight attendant. The plane was forced to make an emergency landing and Scantlin was charged with public intoxication.

Scantlin was adamant he did nothing wrong -- and earlier this week he was vindicated when a judge dismissed the charges due to "insufficient evidence".
