Well, it's a very simple answer: Zero. Nothing. Amnesty has not been officially permitted in Sri Lanka since 2007.
I can say I was actually there in 2008, but as I pointed out, I was there as a tourist. I was clear. I spoke to the Sri Lankan High Commissioner before I went, and so the government certainly knew that I was there. But I was not there as an official Amnesty representative. In fact, as well, I was volunteering as an election monitor with the Sri Lankan process for the election in Batticaloa. But Amnesty has not been permitted to officially return to Sri Lanka since it last was there on a mission in 2007.
