I don't think that's even the smart thing. Because this is set up to receive reports about acts committed by groups receiving weapons from the US, the smart evil thing is to have dossiers of all the human rights abuses of your client states ready the next time you want to negotiate something with them. "It's highly embarrassing that you used the guns we gave you to shoot so many civilians. We might be somewhat less embarrassed to continue supplying you with guns if (your national airline bought more Boeing planes|you sung praises to our glorious leader more loudly in public|you brought a complaint against our adversary in the WTO)."
