A 3rd/4th-class
prostitute. Usually works on his/her own, without a pimp or brothel, thus allowing some form of freedom.
Still, since prostitution is illegal in many countries, streetwalkers often get into trouble with the law. Streetwalkers become
easy prey for rapists, murderers, and other criminals (even corrupt police officers) since they try to keep their liaisons discreet and, being criminals themselves, are not looked out for by
police.
Despite romantic interpretations
like the film "Pretty
Woman," the average streetwalker is quite
run-down and unattractive, from being at the bottom of the social ladder.
