The name of the Brazilian Ambassador in Uruguay is Fernando Campos (the name is revealed throughout the film). But in the beginning of the film right before his kidnap his name appears on a sign at his house as Roberto Campos. The filmmakers probably decided to make this change to avoid confusion with the real Brazilian minister of planning - Roberto Campos.
The International Police Academy meeting, in the flashback, takes place in 1967. But mention is made that "Technological advances have put man on the moon," which would not occur until 1969.
The film constantly alludes to the U.S. official's previous postings in "Brazil and Santo Domingo," and the flashback to the police academy even shows the delegate sitting next to a sign reading "Santo Domingo" along with those of other countries. But Santo Domingo is not a country, it is the capital of the Dominican Republic.
