Preliminary results of PCHR Gaza casualty analysis
While the results are not complete, there is overwhelming evidence that the Palestinian Center for Human Rights knowingly and maliciously lied in its statistics regarding the numbers of civilians and militants killed during Operation Cast Lead. Given its clear biases, the most reasonable conclusion is that the PCHR was not nearly as interested in the truth as it was in demonizing the IDF. The report itself cannot be considered reliable.
Given this information, it is difficult to know whether to believe that organization in other areas.
