More about one of the primary people behind the allegations in this 'report'(same article):
Falk has long been a controversial figure. After taking up the post in May 2008, he compared Israeli forces' actions in the Gaza Strip to those of the Nazis in wartime Europe.
In December that year he was detained at Ben Gurion airport and deported by Israeli authorities after being barred from crossing into Palestinian areas to carry out his investigation.
In 2011 he wrote on his blog that there had been an "apparent cover-up" by U.S. authorities over the Sept 11, 2001 attacks. He later said that he meant investigations must be transparent and exhaustive.
That July he posted a cartoon which critics called anti-Semitic. It was later removed and he apologized for "unintentionally posting an anti-Semitic cartoon".
More recently, U.N. Secretary-General Ban Ki-moon rejected remarks by Falk suggesting the Boston marathon bombings in April were a response to U.S. foreign policy.
Its not Falks report being discussed here.
This has everything to do with Falk. He is the professional anti-Israel "investigator" with the UNHRC, and this "report" directly involves him as it was put out from the UNHRC under his auspices.
