AI is an organization born of a noble ideal in the 70's - to fight against the wrongful imprisonment, mistreatment, torture, and killing of people who's only crime was being in disagreement with their government. AI's work mainly dealt with dictatorships, like Chile under Pinochet, where political opponents and even people who took part in demonstrations or signed petitions, and even their families, would be rounded up and "disappeared" by military death squads.
But the number of such countries is not that great anymore. There are still a few like Iraq and China, but they don't get press attention complaining about them, and in any case, nobody can or will do anything about those countries. So, like the ACLU, they have expanded their horizons in order to keep busy.
One of their favorites is the death penalty in the U.S. OK, I can understand that. But they are already starting to venture far away from their original mandate - the protection of political prisoners and prisoners of concience.
Now they are getting involved in lawsuits protecting the rights of maximum security prisoners having access to TV, Gyms, Cell phones, and other luxuries.
Cases such as these destroy the respect that people once had for such institutions. 15 years ago, I was a dues-paying member of AI, but I wouldn't give them a cent now. Same with the ACLU - until they remember what their purpose is - the betterment of society through human rights - not the destruction of society through "human rights".
The only thing you should feel when shooting a terrorist: Recoil.
