Homelessness in the bay area

I need a 10 page essay talking about how homeless people in SF/Bay Area are policed by citizens living in the city as well as police officers, how are they treated by these different groups? Who treats them worse? You can look on google for articles, documents, magazines or anything else to find examples and how the homeless people are treated like. Talk about what the articles are about and source them in the 10 pages as well.
