If you found out someone you loved was doing drugs -- and you knew you could stop it -- would you grab a hammer and try to rescue that person???
That's the story behind the arrest of Tim Donaghy -- the ex-NBA ref who went to prison for betting on NBA games that he officiated.
Donaghy was arrested in Florida on Tuesday for allegedly threatening a man with a hammer ... but he told police the only reason he was even in that situation was to save his daughter.
