This weekend the Miami Herald had this story about Marc Ecko's constitutional challenge to a Miami Beach graffiti law. And Newsday had this story about how City Councilman Peter Vallone has become graffiti artists' "enemy No. 1." "In January, on a giant billboard near the Manhattan Bridge, they spray-painted in enormous bubble letters a common four-letter insult followed by his name. Also this winter, a graffiti cleanup group's trailer _ which said 'Sponsored by Peter Vallone Jr.' on the side _ was stolen, robbed of its paint buckets and rollers, and abandoned many miles away in Staten Island.
