Most mayors live in big homes. Quogue's may soon be heading to the Big House. George Motz, the village's mayor, was arraigned yesterday on securities fraud charges. Prosecutors allege that Motz bilked investors out of $1.4 million by "cherry-picking" stock trades that benefited his own Manhattan brokerage and investment house. It's bad news for Motz, sure, although it's good news for weekend residents who will have something else besides presidential politics to gossip about over the long weekend. [Newsday]
