Common questions
Is motive classification the same as legal proof of arson?+
No. It is an investigative and behavioural tool used to narrow suspect pools and interpret scene evidence, not a substitute for proving the corpus delicti of arson through fire-cause determination and forensic evidence.
Why is crime concealment treated as a distinct category from profit?+
Concealment arson is set to destroy evidence of another crime such as a homicide or burglary, and it often shows different scene indicators, like fire seated near a body or point of entry, than a profit fire staged around insured contents.
