Wow, this is pretty unreal:

San Francisco City Attorney Dennis Herrera says he has the names of nearly 500 mental health patients released from a state-run psychiatric hospital in Nevada and sent to various California cities.

Rawson-Neal Psychiatric Hospital in Las Vegas transported more than 1,500 psychiatric patients by Greyhound bus nationwide between 2008 and last March.

If this turns out to be true, then it really is very close to human trafficking.
