From the BBC: Argentine Prostitutes Fight Back

http://news.bbc.co.uk/2/hi/americas/6234620.stm

Prostitutes in the Argentine capital, Buenos Aires, have launched a campaign to raise awareness about the difficult circumstances in which they work.

On the ground by the main statue they have daubed the words "No woman is born a prostitute".

It is the title of a book published by two women, Sonia Sanchez and Maria Galindo, which looks at Argentine society and the role prostitution plays within it.

"We're taking control of the streets," said Maria.

"It's a small but important step."

Sonia said: "We're saying enough is enough. Prostitution isn't a job. It's sexual exploitation and it's big business."

Other slogans daubed, then painted over, around the square read: "The pimps rule here" and "Here they exploit the bodies of girls, and the police do nothing".
