The people charged with enforcing the peace deploy lethal force with near impunity at the slightest "provocation" (a child throwing a stone, a car driving too fast); I wouldn't be surprised if IDF forces deployed to the West Bank are trained much like American police officers are, to operate in constant fear and perceive absolutely everything and everyone as a deadly threat to be neutralized. The soldiers themselves are raised in a culture with deeply racist undertones, making them all too ready to view any random Palestinian as a terrorist. Meanwhile, the bureaucracy that should be overseeing them works only to protect them. It's no surprise that things like this happen as often as they do.
Reform in the US is imaginable, I can and do believe, but it's much harder for me to imagine it in Israel - even much of the so-called left in Israel is too radicalized against Palestinians after 100 years of conflict, the Second Intifada, and October 7.
