Factual error: There is no way Utah could have gotten information about Tyler's parents' death, let alone the city and year, from the computer he was using at the FBI office. He would have had to run a separate search for that information using other sources. That type of personal information is not contained in any crime information database.
Factual error: Australian police are never equipped like they are at the end of this movie. The 1st Police on the scene would be Constables, Senior Constables, Sergeants, & Senior Sergeants, & possibly plain-clothes Detectives from the Victorian Police Force. They'd be wearing their regulation uniform & carrying a regulation revolver & hand cuffs. The AFP *may* be liaising, but they're Detectives, too. No high-power weapons; no helicopters.
