Tackling chronic homelessness in L.A.

"Project 50" aims to take the 50 most vulnerable homeless off of Skid Row and put them into permanent supportive housing.

Surveyor Mack Garland pushes on, asking probing questions about health problems and drug use. The answers will be used to create a "vulnerability index," determining who gets housing and who doesn't. To put it bluntly, these questions are meant to identify those most likely to die on these streets in the next year.

Garland also snaps a picture so his group can later locate the 50 fortunate enough to have been determined the most unfortunate and get an apartment.

"You get stuck down here. We're here because we don't accept love and we don't give it," says a man who calls himself "Artist Woods." He's been on the streets for 28 years, he says, ever since he was honorably discharged from the Marines.
