Which statement about arson and origin investigation is correct?

• A. All fires should be considered arson until the origin has been determined.
• B. Arson suspicion is irrelevant if there is water damage.
• C. Origin determination is unnecessary for most fires.
• D. Arson investigation is optional.

Answer: (A)

The main concept here is approaching every fire scene with a mindset that false conclusions can be dangerous: don’t rule out the possibility of arson until the origin is determined. That’s why this option is the best—treat all fires as potentially criminal until you’ve established the origin and cause, so you don’t overlook evidence of intentional ignition. In practice, arson investigators gather and preserve evidence from the scene, trace burn patterns, and determine where the fire started to see if accelerants or other foul play were involved, which is essential even if the scene has water damage from suppression. Water damage does not prove the cause and doesn’t remove the need to investigate origin and potential arson. Arson investigation is a standard part of handling fires, not optional.
