Hitman (2007)

Continuity mistake: In the railway station where 47 is being followed by the FSB, Interpol and the older agent, you see the older agent running down the ramp to platform 9 after 47. His jacket is flying up in the back, and there is no weapon visible. When he stops running, he reaches behind him into the waistband and produces a handgun with a silencer.

Agent 47: The man you've been chasing is a killer. A Ghost. Rumor has it that he works for a group known only as "The Organization." So secret, no-one knows it exists. Takes no sides - yet it has ties to every government. Its sole purpose is the training and conditioning of professional killers. These men are selected at birth - rejects, orphans - all of them - unwanted and disposable. They are made experts in every aspect of combat. And programmed for one purpose... To Kill.

Trivia: When 47 crashes through the hotel window and the kids turn around, you can see that they're playing a videogame. The game is "Hitman: Blood Money", the first mission to be exact.

Question: How was 47's assassination of Belicoff covered up so successfully? There were plenty of witnesses to it and if those same witnesses heard about Belicoff giving a speech or doing something else, they could say that was impossible because they saw him die.
