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: In the opening credits of Hitman, there are several scenes involving children training. Many of these scenes were from footage from the first season of Dark Angel (appeared on Fox on October 3, 2000).

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.
