"facing up to a decade in prison"
Ah, crime is so enticing when it seems easy. What could be better than bringing a USB key full of data that airport security can't possibly control to a country that has no extradition treaty with the place you got the data from ?
Then the uniforms arrest you and you face the consequences of your ill-doing and suddenly, it ain't so fun no more. Especially since you only have yourself to blame for setting foot back in the country you stole the data from. You'd have stayed in China and you'd have it made.
But no, you had to go imagine that you were so smart you'd never get caught. And now here we are, reading about your stupidity.
Enjoy your time behind bars. And I hope you're forbidden from ever getting a passport again.
