It's possible there isn't anyone else involved in Tucson activism that elicits as much hateful diatribe from the right as Isabel Garcia. It's also possible that Tucson's borderland politics and the reasons we should care about the militarization of our border are on our radar because of Garcia's work. By day she works at the Pima County Legal Defenders office, and the rest of her time the attorney advocates for immigrants and the border as co-founder of Derechos Humanos. She defends the invisible and forgotten.
