That was 1000% preventable. You don't get to kill people based on circumstantial evidence without even counting the number of bystanders, without verifying their identity, without doing any level of human intelligence, all easily accomplished tasks, and then claim that you did everything you could.
It's absolutely clear the US did not give a single shit about civilians. Many US and coalition soldiers were even happy to kill civilians. You don't authorize a policy of systematically killing first responders ("double tap strikes") and then claim you were trying to minimize civilians casualties. It wasn't a mistake, it was knowingly just not giving a shit.
It's clear where stand: "Things happen in war"
