In March 2004a year after the war in Iraq beganMother Jones published a photo essay of wounded soldiers by Nina Berman. Unfortunately, Ms. Berman has been busy since then and has compiled an entire exhibit called “Purple Hearts.” That exhibit is now on display at Columbia University in Manhattan (funded in part by George Soros’ Open Society Institute). Ms. Berman will be participating in a panel discussion tonight. If you’re in Manhattan, go. If you’re not, check out the photographs we ranthey’re seriously powerful stuff.
