What more evidence can we need?

More than just an accusation from some random Palestinian group!

Re. Warsi, I did know that many people do not support Israel on this.
Given the reporting, it is amazing anyone does!

Washington Post.
"The media has engaged in journalistic malpractice by reporting casualty figures for civilians coming from Gaza as gospel. The figures come from the Gazan Ministry of Health, which is controlled by Hamas. The Ministry of Health counts everyone not in uniform as a civilian. Most Hamas fighters don't wear uniforms. The UN is sometimes sourced for the figures, but the UN gets its figures from … the Gazan Ministry of Health. Contrary to early reports that 80% or so of the early casualties were civilians, Al-Jazeera published names and ages, and about 3/4 were men of fighting age (16-50), compared to a rough estimate of 20% of the Gazan population (40% to 50% of which is fourteen and under). Some of those men were undoubtedly civilians, but it strains credulity to believe that 80% of the casualties were civilian but just-so-happened to be overwhelmingly fighting-age men. (Here's the most recent analysis from the IsraellyCool blog). For that matter, how do we know that the Minsitry of Health isn't counting deaths from natural causes as deaths from Israeli actions?"
