Version 2 of the transportation system is well known in outline. Undesirable elements are disappeared to remote islands, whose people don't want them there, and whose police, to the extent that there are any, aren't willing to protect them.

The people in charge of this go to extreme lengths to prevent anyone finding out the details, which is strong circumstantial evidence that they're doing something very wrong, and that they know it.
