- Himself - Forensic Psychologist: Most serial killers - men who kill men - are themselves gay. Most heterosexual serial killers kill women. What often happens in a case like this is that Ireland himself may be homosexual or may have a strong aspect of homosexuality to his personality but can't accept it. He doesn't want to accept that, and so there's a part of him that he hates, and by killing others he's sort of reassuring himself that he's not gay, that's not part of his personality.
- Himself - Criminologist: There's always this sense of a kind of perverted moral hierarchy, a desire to be someone in a community - and, of course, performing the role as an informal neighborhood patrol officer would give Ireland that sense of paying something back, that sense of having some standing.
- Narrator: But no one could foresee the tragic and brutal consequences of Colin Ireland's turbulent youth, criminal career, and brushes with London's gay community.
- Himself - Forensic Psychologist: There's a clear narcissistic quality to Ireland. He, uh, he wanted to take credit for this and, um, he was very proud of what he did - as are many of these, uh, serial killers. They're very pleased with themselves.
