Goldstone in La-La-Land

Page 134 of the report:

439. The Mission also addressed questions regarding the tactics used by Palestinian armed groups to the Gaza authorities. They responded that they had nothing to do, directly or indirectly, with al-Qassam Brigades or other armed groups and had no knowledge of their tactics. To gather first-hand information on the matter, the Mission requested a meeting with representatives of armed groups. However, the groups were not agreeable to such a meeting. The Mission, consequently, had little option but to rely upon indirect sources to a greater extent than for other parts of its investigation.

Translation: the Mission=the Commission
Palestinian armed groups=Hamas, Islamic Jihad, perhaps el-Aksa Brigades. Anyone fighting Israel.
Gaza Authorities=Hamas.

So the Commission didn't talk to the Israelis, it didn't talk to any Palestinians who might have admitted to fighting the Israelis, the "authorities" had no connection with the fighters, none whatsoever, no Arab-language documentation of government was sought nor seen, no Hebrew-language documentation was seen, no Hebrew-Arabic intelligence documentation was seen.

Of such materials are important international documents forged.
