A red van drives slowly beside a female pedestrian matching the speed of her steps. When no response is received. the vehicle signals with a flash of the headlights. The vehicle finally turns away from the woman. This type of stalking is part of the extreme social toxicity of prostitution. Stalking johns have no respect for the age of the target, the hour of day or the day of the week. Seen here is an event on October 9, 2007 in the Landsdale Neighbourhood of Hamilton, Ontario.
