Yeah, the security guard. L and O was so good back in the day when it first started. I remember seeing Phillip Seymour Hoffman for the first time playing a doofus. But in the whitlock ep in question, Briscoe and Logan are interviewing everyone who may have seen the kid and Whitlock was just one of many who said "yeah, I saw him, then he went that way" kind of thing...and then on to the next person - then they end up circling back to Whitlock's character and he just drops a bomb on the detectives - "Well, I had to kill them, they were looking at dirty magazines" or something like that.... I wish I could find the clip.
