Texas prosecutors have dropped charges against all of the alleged pedophiles who were caught on hidden cameras in a sting by NBC's Dateline. The sting, conducted in a house wired with cameras and microphones in Murphy, TX, resulted in the arrest of 24 men who thought they were meeting underage boys and girls for sex after engaging in online chats with the decoys. In one instance, a deputy D.A. in a neighboring county, Louis Conradt Jr., who had apparently engaged in sexually explicit online conversations with a decoy claiming to be a 13-year-old boy, shot and killed himself when police arrived -- a Dateline crew in tow -- to arrest him. "The fact that somebody besides police officers were involved is what makes this case bad," Collin County District Attorney John Roach told the Associated Press Thursday. "If professionals had been running the show, they would have done a much better job rather than being at the beck and call of outsiders." Chris Hansen, the reporter who fronted the Dateline piece, told the wire service: "I don't want to get involved in the D.A.'s business or the police business. ... I can tell you in the other locations [where Dateline conducted similar stings], these issues did not come up."
