Charles, did you write this piece backwards? After finding you subject, homeless mentally ill people, Choices found you the most sympathetic person they could. So that this could end on the most hopeful note possible. 

I challenge you to now interview the least sympathetic person. Go to the Sleep off center and talk to a "frequent-flier" Ask if they have ever been offered help to get off the streets. If they want to stop camping, begging, and drinking.

In six months go back and see where they are. Were the long term outcomes any different? Just guessing, but Ensley is going to listen to those voices, and get kicked out of that apartment. (He should go back to CA so his family can care for him.) And the frequent-flier will be on the street still.
