A rising number of homeless people who are mentally ill are not able to receive treatment in the US.
Most homeless shelters only take in people who are deemed mentally stable and do not offer psychological services.
It is estimated that more than 50 percent of people living on the streets are mentally ill.
Many even break into homes, hoping to be sent to jail to get free meals and medication.
