"Magic stone" in that case was brought up not by the judge, but by one of the alleged victims who was 6-years old at the time. The police presumed the "magic stone" was some sort of a sleeping pill or drug given to the child in order to make him compliant during the alleged assault. Kudos to the appeals court for throwing out the conviction.
A better example for foreign pilots might be the
Gol 1907 mid-air collision with an Embraer Legacy in Brazil. The Legacy pilots (both American citizens) were arrested, charged and convicted for their role in the collision, even though they operated the plane exactly per Brazilian ATC instructions.
That conviction was unfortunately upheld on appeal, although the pilots were allowed to return to the US.
