All wars have their share of criminal actions. Our own US military convicted soldiers for isolated incidents of crimes including rape and murder in Iraq and in every war before. Let's not forget the photos of mistreatment of prisoners at Abu Gahreb. The sad truth is that all wars are wrong and no army is 100% free of abuse. I don't advocate investigating the entire IDF but certainly investigating individual acts of reported abuse. The US also reviewed its Rules of Engagement and modified what was needed and allowed. Although Israel is fighting terrorism it must remain within the law just like every other country. The terrorists will never do so by definition but we must aspire to to a higher moral code or we become as evil as our enemies.
