Are you actually dismissing Human Right Watch as a valid source - after you have used it yourself in the past, re. Israel's Blockade of Gaza.
The incident you refer to HERE was spread by pro-Israli bloggers, was related to his family's interest in military nterest and was found to be no more than a Israeli regime generated smear campaign that has also targetted the U.N. and a host of human rights organisations.
It was a deliberate campaign set up by Israel to undermine Human Rights organisations which were critical of Israeli terrorism.   
The last of these stunts was an attempt to close The International Court of Human rights, which would leave the world unable to try any International criminals.
