America's Most Wanted host John Walsh challenged viewers Saturday to help capture the perpetrators of a string of denial of service (DoS) attacks that afflicted Yahoo!, eBay, CNN.com, and other popular e-commerce sites in February. The show is known for the often-violent dramatizations and reenactments that accompany weekly profiles of fugitives and unsolved crimes. Each week, host Walsh encourages viewers to phone in tips to a toll-free number. America's Most Wanted boasts 609 arrests in its twelve years on Fox, with fugitives often apprehended within hours of a show's airing.
