SEATTLE (AP) — Superheroes are no longer just in comic books or on movie screens.The patrolling of city streets by "real life super-heroes" has been getting more popular.That's thanks largely to mainstream attention in movies and the recent HBO documentary "Superheroes."But recently a self-proclaimed superhero in a black mask and matching muscle-suit — Benjamin Fodor, better known as Phoenix Jones — was briefly jailed in Seattle for investigation of assault.That shook the small community of masked crime-fighters across the U.S.Many fret that even well-intentioned vigilantes risk hurting themselves, the public and the movement if they're too aggressive.Edward Stinson is a writer from Boca Raton, Fla., who advises real-life superheroes on a Website.He tells them to build trust, work to earn the title, and take some kind of oath.
