The Apache gunner did not know that they were firing on a journalist, they had believed they were engaging a legal target and were doing so within given rules of engagement. Which is legal. It's a tragedy that they were mis-identified, but again, not a warcrime. Had they known they were non combatants and fired on them still, that would have been a warcrime.
