Mike Rhodes got closer than a lot of people to understanding life on the streets.
For more than a decade, he documented homeless people and their treatment in Fresno, for the Community Alliance newspaper.
The treatment including the occasional bulldozing of homeless encampments by the city.
Rhodes compiles his work from those years into a book called Dispatches From The War Zone.
He calls the Exchange to talk about what he saw, and what he makes of it all.
