Ah, what the hell. I'm not going to let a little bit of emotional blackmail shut me up.

This is a small sampling of what I found when I did a Google search with the key words: "ratio" + "killed" + "Israel" + "Palestinian"

Fairness and Accuracy in Reporting

This, by the Israeli human rights group B'Tselem (a small excerpt from the article in contained in the above link).

The devastating human toll of such "retaliations" makes these imbalances all the more striking. According to the latest estimates from the Israeli human rights group B'Tselem, 897 of the Palestinians killed from September 29, 2000 though March 30, 2002 have been civilians. Israeli security forces killed 823 of those 897 people, including 192 children. B'Tselem records that 253 Israeli civilians were killed by Palestinians in the same period, including 48 children. At least 16 of those 253 people were killed by Palestinian National Authority security forces or persons reportedly linked to them. B'Tselem notes that these figures include neither suicide bombers nor Palestinians who "died after medical treatment was delayed" by Israeli forces.
