One little known fact it's that in Israeli army there is heavy involvement of lawyers in ongoing activities to make sure that things are as kosher as possible with regards to rules of engagement and international law. Ground units I believe have embedded video operators for same purpose.

Also there were long project (probably still ongoing) which tried to determine the "acceptable" amount of collateral damage (civilian casualties) under different operational scenarios, e.g. if there is somebody who about to shoot rockets into Israel or cross border to explode in a bus or go through underground tunnel to Israel just to shoot somebody how far is it acceptable to go to prevent it.

The bottom line, nobody in Israel interested in civilian casualties on Palestinian side, both because people are not a blood thirsty monsters and because every little incident will be in the news everywhere around the world and nobody really interested in it.
