Amnesty - for a positive impact, a sample of their success stories:-
"I was beaten and verbally abused in detention. After a few days, the guards asked me: 'do you know that your name is all over the internet?'. After that, I was treated better by the guards before being released. The appeals sent by Amnesty members definitely had an affect on my case."
