Plot hole: The kids in Soneji's class use an encrypted GIF algorithm to pass notes to each other and that "drives the teachers crazy", since they are unable to catch cheaters that way. But how do they do that? Easy, they have a message system in place installed on their workstations, that warns them with a big pop-up that they've got "A new message"! It would be easy to sanction and prevent the cheating by simply removing the chat application, no matter if they use it to chat directly or pass Michael Jordan photos as shown in the movie, which they have no business doing during an assignment anyway.
Plot hole: When Marty, Ali and the hitman go back to the crime scene, they go over to the water where they threw Bobby's body. Marty throws up, leaving his DNA at the crime scene. And since he was Bobby's best friend, he's the number one suspect.
Plot hole: The female employee says he's going to inherit everything, he gets it all. No he only gets 51%, the 7 dwarfs still make many decisions. (00:10:37)
Plot hole: In the opening scene, Travolta forces the SWAT team to let him go when he brandishes the remote detonation device he's holding. That's fine - but upon numerous occasions in his opening monologue (lighting a cigar, checking and smacking his watch), he isn't holding the device for lengthy periods of time. Why didn't the SWAT team shoot him at that point given they're covering his every angle with guns?
Plot hole: Early in the film, we learn that the former prostitute Annie Crook is married to and has an infant daughter (Alice) with Prince Edward Albert Victor. Secretly outraged, Queen Victoria dispatches various high-ranking operatives to eliminate this potential royal scandal. To that end, Prince Edward Albert Victor is secreted away, and his wife Annie Crook is kidnapped and barbarically lobotomized. We then learn that he baby, Alice (who was fortunately in the care of two other prostitutes at the time of the kidnapping), was sent to live with the parents of Annie Crook, no doubt saving the baby's life. That is the last time we hear of baby Alice until near the end of the film, where we are puzzled to learn that Alice was not sent to live with her grandparents at all, as stated earlier. Rather, the prostitute Mary Kelly took baby Alice away from an orphanage to raise as her own. No explanation is offered for this discrepancy.
Suggested correction: Vomit doesn't contain DNA, unless said vomit contains blood.
Untrue. "While not all these bodily substances provide ideal DNA samples, testable DNA can often be extracted from all of them. In every case, what is being tested is the DNA contained in cells of human tissue, whether found on their own or carried by another substance, like earwax, sweat or mucus. Shed cells are also found in urine and feces, vomit, and even tears." https://www.nytimes.com/2010/11/02/science/02qna.html.
