That question was not asked in a vacuum but specifically to address the biases and lack of credibility of the UN human rights bodies.
Let's keep it on topic. So if the UN is so ineffective what will it do in Ferguson? Agenda 21 the cops?
So why should we trust them to deal in any way fairly with the issue of Ferguson?
What exactly can they do and why do you think that they can do anything? And why aren't you bringing up other examples if you are serious about discussion of the Ferguson situation?
Let's stay on topic here and talk about how effective a UN conference in Switzerland will be in the unfolding events in Ferguson (and NOT bring up the Middle East).
In my opinion it will not have any effect at all beyond rustling the feathers of the most extreme wingnuts, intellectually dishonest, and the plain stupid.
