Seeing as the dude at a whole order of donuts before that, it is likely his version of one bite would have led to him licking up the crumbs from his face... After he scarfed the whole thing down...
The dude literally has all the evidence he did it on his face and coming out of his mouth, and he dares say: It's not me. Man is the type to eat your order outside your door and claim that it was a raccoon, even if it was on video...
