Jena 6

from the website:

In September 2006, a group of African American high school students in Jena, Louisiana, asked the school for permission to sit beneath a "whites only" shade tree. There was an unwritten rule that blacks couldn't sit beneath the tree. The school said they didn't care where students sat. The next day, students arrived at school to see three nooses (in school colors) hanging from the tree. (Please note, the tree above is not the tree, but a tree at Jena High School.)
