@Fil Albuquerque,
My pragmatic approach would be for all the world leaders, say the leaders of the G20, initiate a statement demanding that Pakistan release this woman to some safe custody or suffer severe trade sanctions. Perhaps those who sell weapons to Pakistan can start. We should also focus on China with their human rights abuses, instead of joining with them economically.
Probably the only outlet is to march in the streets with Ghandi or MLK. This race of humans in it's ability to 'look the other way' has a disturbing trait.
In fact, it is tolerated.
