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.
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.

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.
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)
