Equally, are we going to pretend that bombing a school which is not a Hamas HQ and then, after the news comes out that they killed 10s of children, telling us it was a Hamas HQ is not something the IDF would do?

Does it really makes sense to trust the guys who chose to blow up a building full of children when they give us an unverifiable self-serving justification for their action?!

Even if you are partisan and in your heart of hearts feel deeply that Israel are the good guys, how can you be sure they've investigate enough and know with enough certainty that that's a Hamas HQ to take a decision that they know is highly likely to result in dead children as collateral damage (assuming you are unable to question the morality of those who think dead children as collateral is acceptable)?

The Death Penalty in the the US has a huge system in place not just to judge a possible perpetrator but also of appeals to try and make sure a single person is not executed if he or she turns out to be innocent and even then death is a highly exceptional and rare penalty, so how would it be fine to kill a bunch of innocent children on a non-existent standard of proof (the killers are judge, jury and executioner) that their school contains a Hamas HQ, with no appeals, no independent verification, no nothing but the word of the very people who think dead children is morally accepetable as collateral.
