Other mistake: At the start of the film Danny is caught trying to smuggle diamonds into Liberia. The Liberian border guards catch him, but somehow he ends up in a Sierra Leone prison instead of a Liberian one.
Blood Diamond (2006)
1 other mistake
Directed by: Edward Zwick
Starring: Jennifer Connelly, Leonardo DiCaprio, Djimon Hounsou, Kagiso Kuypers
Factual error: Throughout the entire movie, the vehicles are driven on the left side of the road. Sierra Leone drives on the right. This is likely because the filming locations of South Africa and Mozambique drive on the left.
Danny Archer: So you're a fisherman, ha? What do you catch mostly?
Solomon Vandy: Fish.
Question: When Solomon met with Michael Sheen, he and Maddy were staging a set-up to expose him, as well Van De Kamp. Since what he and Van de Kamp did were technically illegal, wouldn't Solomon be arrested for giving him the diamond?
Answer: More often than not, lesser criminals are granted immunity in order to bring down greater criminals or complete criminal organizations. From a criminal justice standpoint, it makes sense to let Vandy off scot free if it helps you put the big fish in jail.
