Williams' former colleague Ronald Myers, a 31-year FBI veteran, praised his work to the Los Angeles Times. "He is one of the sharpest agents I have ever met," Myers said. "Anyone in FBI management who wouldn't take what Ken Williams said seriously is a fool." Since the trial, Williams has continued working quietly. "It's been my past experience," Williams told the court, "that the smallest bit of information that comes in could later turn out to be the most important piece of the investigation." That's a lesson Williams' bosses learned too late.
