Hell, there are plenty of people dumb enough to video themselves or friends breaking and entering, beating up people and stabbing people, stealing cars, and the like and POST THESE VIDEOS TO YOUTUBE OR ON SOCIAL NETWORKS.
People do in fact cross borders with ridiculously incriminating things on their laptops and phones, such as photos of the kiddie sex tourism, email or logs of chats from the person who talked them into carrying drugs, and things like that.
