Continuity mistake: The main bad guy has Alex cornered in Mrs. Hess' garage. Look at the clear plastic cup behind Alex. One shot the cup is upright, the next it is on its side.
Continuity mistake: When the villain with the long hair is being electrocuted by the wire outside the front door, in a close up shot his ski pants are on fire, then in a further away shot, they are not, then in another close up they are on fire again. (01:03:05)
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.
