Plot hole: Whistler's powers are not fully explained, but most certainly he has no god-like abilities or is omniscient; the rest of the movie shows he is not. But Jack's first run-in with a Trancer in 1985 LA makes no sense then; unless Whistler was mentally controlling every mall Santa in LA, he had no way to know where "Philip" would end up. If he did (and again, how could he; he doesn't have the power to control legions of Trancers), he would have capitalized on it catching him in the act with the police, too.
Plot hole: The 'medics' carry the body bag that is supposed to have the body of Evil Santa inside, but Whistler vaporized it. Somehow, they fail to notice that the obese man weighs like a feather and the bag is deflated and empty. Moreover, the other Trancers vaporize within seconds from their death, but that one, and only that one, took minutes or even hours to disappear, only with Whistler's direct intervention. (00:25:00)
