Since the summer of 2005, she has been touring around the United States and abroad with a presentation and has written a book (Witness in Palestine) describing her personal experiences, observations, and photographs from eight months of documenting what she described as human rights violations in the West Bank. Noam Chomsky’s review of Baltzer's book states, "Even those who are familiar with the grim reality of the occupied territories will quickly be drawn into a world they had barely imagined by these vivid, searingly honest, intensely acute portrayals”,[better source needed] while Tanya Reinhart author of "Roadmap to Nowhere" call it "Moving and vivid.” Mark Chmiel, teacher at St. Louis University and Webster University and author of "Elie Wiesel and the Politics of Moral Leadership", has also written about Baltzer's book.
Baltzer's activism centers around nonviolent protests, as well as providing documented information to those interested in the Israeli-Palestinian conflict for the purpose of education and encouraging dialogue towards taking action on the issues. She claims that critical information doesn't show up in the United States mainstream media. According to Balzter's own account, when she first went to Israel on a free birthright trip in January 2000, she saw "a beautiful picture of Israel" but nothing of what was happening to Palestinians. "A Jewish student-life coordinator at Hillel, called the SJP event very well organized and well attended. It seemed very non-threatening and very non-violent. (Speaker) Baltzer made an extra special point that just because she was anti-Israeli policy, it doesn’t mean she is anti-Jewish."
