COLORADO SPRINGS — Panhandlers, with their crumpled signs, coffee cups and pleas, are as customary a sight in many American towns and cities as Starbucks or McDonald’s. But for one Utah homeless man, the right to ask people for money has become a personal legal crusade.

Steve Ray Evans, who uses a sign to ask drivers for money, has been successfully suing Utah cities that have cited him for panhandling, arguing that his right to free speech is being violated by a state statute that bans soliciting near roadways.

“This is my only source of income,” said Mr. Evans, 54, whose sign reads “Starving Please Help!” “I do it for survival purposes. I feel as though a lot of other individuals depend on it, too.”

Mr. Evans said he had received more than 50 panhandling citations, and cases like his have become increasingly common of late. With the downturn in the economy, cities across the country have been cracking down on an apparent rise in aggressive panhandling, while advocates for the homeless and civil liberties groups contend that sweeping bans on begging go too far.
