LOS ANGELES — From his home across the street from a homeless shelter in Venice, Shawn Stern sometimes turns on his video camera to document a disturbance that has grabbed his attention.
On Nov. 6, he recorded a gray-haired woman walking down Main Street, screaming and gesturing at passing cars.
Ten days later, another woman sat on the sidewalk, surrounded by three outreach workers, screaming at them that she did not want their help. Later, she too was walking down the middle of the street.
