Because the U.N. Rights Commission which is tasked with monitoring compliance by it's member nations with the U.N. Human Rights Accord, because it can't get the U.S. to issue the yearly report it is required to do under the accord, for the first time in history the U.N. has requested groups which monitor human rights violations to submit reports on the U.S.'s human rights violations. The reason the U.S. has been failing to report it's own violations is clearly because it has become one of the world's major human rights violators. This is a sad comentary on a country that at least used to portray itself as a supporter of human rights.
