I was liking this til I got to hm explaining how Luminol works, is just plain wrong. He says you spray an area with Luminol spray, use a blue light on the sprayed area, and if the area in the lighted area lights up then it means blood was there. You don't need a special light, luminol fluoresces blue on its own.. and it also can indicate if an area has been cleaned, so this large area of blood, may just be bleach..
