In SR4A (p119, Skill Ratings Table), it lists Damien Knight as an example under Rating 7, in the "Social Skills" category. However, in Street Legends Supplemental he's listed as having "Influence Skill Group" 6, Intimidation 5, and no Leadership.
Even the 6 vs 7 aside, I really doubt Damien Knight has no Leadership skills.
EDIT: I'm a silly person.
