Trivia: The film was conceived with Macaulay Culkin in mind to reprise his role as Kevin. Culkin refused, however, thinking that a third adventure with the character would be too unbelievable, and also feeling a bit burnt out with the role. Thus, the film was rewritten to focus on a new lead.
Trivia: At one point in time, the movie was going to be made for television and serve as a backdoor pilot for a potential "Home Alone" TV series. But this idea was dropped for a traditional theatrical film. The following movie, "Home Alone 4: Taking Back the House," was written to be a stand-alone movie but was retooled to serve as a backdoor pilot for a potential TV series. (Which of course never happened).
Trivia: One of the many early concepts for the film after Macaulay Culkin dropped out was to have Joe Pesci and Daniel Stern returning as the "Wet Bandits," who would torment Kevin's young cousin Fuller, but this was dropped as none of the actors wanted to return for a third film.
Answer: Because it's just a movie, it's a comedy, and the filmmakers are not concerned with exact, realistic details. They expect the audience to just enjoy the silliness and not be overly concerned about reality. The two other Home Alone films employed similar "suspension of disbelief" in the plots.

Exactly like what happened to the guy that gave them the chip. Wouldn't he be arrested too, but we don't hear anything about what happened to him. I'm assuming since he had a plan to catch he was going somewhere he can't be extradited.
The guy who hired Beaupre and his team was in China the whole time, so he couldn't be extradited to America since China has no extradition treaty with America.
