Soap has a criminal past.
- Look at how insistent Soap is at the beginning of the film to refrain from any unlawful behaviour, and how many precautions he takes to avoid getting caught or recognised during the robbery (for example, he's the one who thinks to buy some balaclavas, and is the only one who wears gloves). He also delivers a rather detailed monologue on the psychological effectiveness of using knives in the robbery. At some point in the past, Soap was involved with some kind of robbery or other crime and was either skilled or lucky enough to not get caught; his desire to keep his hands clean is a result of him wanting to lie low, in order to not give the police a reason to re-open their old case files.
- He does actually get arrested at the end (along with Ed and Tom), but is released pretty quickly after the traffic warden identifies (the bodies of) Dog and his men as the robbers.
