Is that it though? When one has historical reasons to expect being attacked, one must be vigilant and one must be trigger-ready.

A professional looks at and understands the situation as it exists now. A professional is trained to not get into situations where fear controls them. Your argument is a compelling one that either these are not professionals or that they are professionals and are doing this on purpose. The stats today clearly show the massive difference between danger to Israeli personnel and Palestinians. Israel at this point has either failed to train professional forces that seek to deescalate and avoid dangerous situations or is training forces to find situations they can claim fear as a justification for murder. So, pick. They are either amateurs at which point it is a deplorable to put amateurs with this much force near a vulnerable population or they are professionals trained to do exactly this, find ways to kill a vulnerable population and claim self defense.
Yes, American police use these kinds of justifications when innocent people are killed too. It's absurd (watch Surviving Edged Weapons [0] some time) either way.
The reality is, if you have soldiers mowing down children throwing rocks, mowing down families driving around, mowing down kids playing football, mowing down toddlers in their bedrooms, mowing down hundreds of people each year [1], you've over-indexed on vigilance and under-indexed on the value of human life. You're not trigger-ready, you're trigger-happy.
