Homeless Camps Called a Fire Hazard:  With wildfires sweeping across southern California, residents of San Clemente are asking local authorities to clear out homeless encampments because they pose a fire hazard.  Fred Swegles of the Orange County Register reports that the calls for clearing out the encampments came after a November 25 fire burned seven acres in a rural area frequented by vagrants near homes and a high school. There has been a significant increase in the homeless population in California over the past five years, with an estimated 55,000 living on the streets in Los Angeles and over 9,000 in San Diego.  A large percentage of homeless living in rural areas lite fires for cooking and heat and many smoke cigarettes. The homeless population also includes drug users including those who smoke crack cocaine and marijuana.
