Mark aims a telescopic sighted rifle at Mike at the port yet a laser (sight) is projected onto Mike, forewarning Ryan to shove him away. Rifle scopes do not project a laser beam.
When Ryan investigates the room in which Carrie was being kept before the trial, he notices that the rug was damp with bleach. Despite this, the color of the rug was still a consistent dark shade of pink. Bleach would have lightened the color in the affected spot noticeably.
