“Over the past five years, the state of Nevada has transferred to other
states approximately 1,500 patients discharged from its state-run
Rawson-Neal Psychiatric Hospital, including 500 patients that Nevada sent by
Greyhound bus to cities and counties in California,” said the lawsuit filed
September 2013 by Herrera in San Francisco Superior Court. The revelations
led to the loss of the hospital’s accreditation. It has since been
reaccredited.
The patients, many of whom were mentally ill indigent and not California
residents, were sent to various destinations with no arrangements for when
they arrived, according to the lawsuit.
Even when homeless aren't bused to CA, it beats most of the country: generous public services plus weather rarely below freezing. So people migrate here from all over, yet we alone pay for the services people need.
My SO had someone chase her around a car attempting to stab her with a screwdriver. SF police, typically useless, didn't arrive until he was long gone. People aren't exaggerating when they say big pieces of the city are unsafe.
