Visible crew/equipment: Alex fixes the TV to show a camera picture. The next scene when two of the criminals pull up in the car next to a mirror, a crew member is blatantly visible in the reflection, if you look closely on the left hand side. (00:37:10)
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.
