I think Tibetan are victim in ths case. They dont have their own country so they have to live in others country forcefully, unlike us, who can go back to OUR COUNTRY when we want.
Anyone has the right to proest infront of UN. we all know Nepal government has very good relation with Beijing and they are showing faithfulness to Beijing by beating the tibetian refugees here. Nepal government is just doing there "noon ko sojho".  But beating anyone with suh inhumanity is not acceptable in this 21st century for any reason.
I regard Tibetian as very helpful and easy going people. And peaceful at the same time too. I cannot say if FREE TIBET is good for Nepal or not but its definately good for the TIBETIANS.
