I'm not talking about the reporters. Never have. While that was en error in hindsight, shit happens in war. It's my belief that even though american aircrews are notoriously trigger happy (just ask e.g. your British allies, who thought the US Air Force was more dangerous to them than the enemy) had they been tried for that they would not have been found in error.
I'm talking about their other behaviour, especially firing on the van, where the air crew in the run up clearly demonstrates that they know the rules of engagement as they're clearly heard saying "Just pick up a gun so I can shoot you" (paraphrase) in reference to one of the wounded men crawling away along the curb. When the van then enters, and stops before that crawling man, then the air crew (as they needed to according to the rules of engagement) contacts higher command to secure permission to fire, and lies to their CO, by stating "They're picking up weapons and bodies". They clearly weren't picking up bodies as the man they stopped by was very much alive at that point, and they weren't anywhere near a weapon. And the CO hearing this gives them the permission to fire.
It's a flagrant and quite clearly indefensible violation of the laws of war and their own rules of engagement, and they knew it.
Now what the attacks on Paris has to do with this, I'm at a complete loss to understand. The incident we're talking about happened years ago, long before any attack on France. And what other people do, at other times, and at other people likewise can't guide our behaviour. While we cannot take responsibility for other people's behaviour, we can, and should take responsibility for our own.
Quite frankly it reeks of the sentiment that was heard just after the Oklahoma city bombings, that "We should just bomb random cities in the middle east." Which made quite a few quip after the identity of the attacker became known that it would then by the same logic be OK to just bomb random cities in the mid west? The British were heard saying the same thing in reference to the IRA "troubles", that just parking the Hermes off the eastern seaboard and with a few well placed strikes in south Boston IRA's funding would dry up in no-time flat...
Now, if that behaviour is unconscionable, why would large scale indiscriminate bombing in the middle east be a) defensible and b) a good idea?
When it comes to the IS the solution is very simple. You broke the country, you bought it. Get your lazy arses back in there and finish the job.
