Adam is Alive???

In Saw Adam was shackled on his left leg. This was established in Saw III when Jigsaw told Amanda to put his left leg in the shackle.

In Saw II you see Adam's corpse its hit right leg that's in the shackle. Now also the bullet wound is in the middle of the corpse body not in the shoulder. Detective Tapp was shot square in the chest could it maybe his corpse switched out with Adam???

In Saw III Jigsaw tells Amanda I cleaned up your mistakes and forgave you for them. One mistake we know he cleaned up was Detective Matthews who she thought she had killed or left for dead. is it possible she thought she had killed Adam as well and left him for dead and jigsaw cleaned it up to???

There are a lot of photos in the Saw movies after Saw II, could Adam be behind that??? Would Dr. Gordon really leave Adam in the bathroom????
