Character mistake: When Zeke is investigating the pickup with the spiral painted on it, and the pig falls out, he goes to grab the box left by the copycat, and it is with his bare hands. In the next shot, it shows that he used a folded glove to pick it up. (00:39:30)
Character mistake: Zeke makes the bold claim that "John Kramer didn't target cops." This is completely and utterly false, and a cop like him should know better. Kramer repeatedly targeted cops. In fact, both "Saw II" and "Saw IV" have officers (Detective Mathews and SWAT Commander Rigg) as Kramer's main target.
