Back in 2011 he cancelled a trip to switzerland after some human rights groups had threatened to have him arrested and tried if he ever set foot there.
some human rights groups had threatened to have him arrested
I wasn't aware that random groups had arrest powers in Switzerland.
Well they don't. Not sure if the swiss legal system is set up to prosecute criminals in universal jurisdiction. In germany around 2006, a private citizen, Wolfgang Kaleck filed a lawsuit against Donald Rumsfeld and other criminals who perpetrated abu ghraib and guantamo, which the German government only barely managed to ignore because none of the targets of the lawsuit were actually on german soil at the time the suit was filed. I'm also curious to know if that ever went anywhere.
Actually they did one time when one of the ruthless generals of Algeria was got arrested in Switzerland because of two human rights peoples. but it was released.
