"Women Are Heroes" is done by a 25 year-old artist who goes by JR. He photographs women across the world, in countries like Sudan, Sierra Leone, Cambodia and Laos, as well as Brazil. Then he prints extreme enlargements of the images, and wallpapers the sides of buildings in the neighborhoods of the women he documents… but then also posts them in a very large format in Western cities.

In Brazil, thousands of killings by police are going largely unpunished because of public approval for a perceived crackdown on crime, reports the U.N. envoy, Philip Alston. Clashes with police killed a record 1,260 civilians in Rio de Janeiro state last year.

JK's previous project, "Face2Face" made portraits of Palestinians and Israelis doing the same job and posted them face to face, in huge formats, in unavoidable places, on the Israeli and the Palestinian sides. "Face to face" is necessary. Within a few years, JR will come back for "Hand in hand".
