    Your own link shows that the convention is, in point of fact, an annex to the GCs. You even bolded the relevant text. I would consider that a separate entity, but YMMV. Apart from that, what the GP meant was the International Code of Medical Ethics, which is neither part of the GC, nor an annex.

    Moreover, the singular term "Geneva Convention" generally refers only to the fourth (and most recent) GC, circa 1949. "Geneva Conventions" plural can refer to all four treaties, however precise usage should involve referring to the specific annex you listed as "The Convention on Certain Conventional Weapons". And yes, that is pedantic legal nitpicking on my part, but any lawyer worth his or her salt will back me when I say that precision matters a hell of a lot more in law than in any other part of language.

    My point stands that using the singular phrase "Geneva Convention" to refer to all four treaties and their annexes is incorrect, never mind referring to other unconnected laws as such. Moreover, most of the things attached to the GCs have their own identifiers. If it is absolutely necessary to refer to the entire body of international laws of war, other terms should be used instead.

    I will concede however that I should have used a phrase other than "literally all there is to them", since it's clear to me now that those words can be interpreted as "there is nothing else remotely connected to the GCs other than the above", which is not quite what I had in mind when I posted.

    Noted, thank you. I'll make sure to pay closer attention to the wording, as I'm only marginally familiar with the convention. Though I wouldn't be surprised if the doctors were somehow connected to the state.

    For future reference, whenever somebody tells you that "the Geneva Convention says you can/can't do X", that should immediately set off your bullshit detector. The conventions have become a kind of layperson shorthand for "international regulations", so everybody and their dog has some pretty weird notions about what they cover. People see these references to the GCs, assume the person making the reference knows better than they do, and the cycle continues.

    The Geneva Conventions cover the treatment, in wartime, of prisoners, wounded, civilians and medics. That is literally all there is to them.

    Now, back on to the topic at hand, medical tourism is one of those intractable problems that nobody wants to admit can't be fixed, irrespective of whether they ought to be. The US cannot control where its citizens travel, or what they do in other countries - look for example at the number of American tourists in Cuba, most of whom stopped over somewhere else en route to circumvent the restrictions on traveling there. Actually, this isn't specific to the US; no first world democracy can effectively regulate the actions of their citizens going abroad.

    Thus, the only party in this whole affair who have any say in what Americans visiting Thailand can and cannot do is the Thai government. Meaning the only way Americans will stop going to Thai hospitals for dodgy untried treatments is if said hospitals are no longer allowed to offer them (either due to Thailand adopting USFDA style regulations, or by it prosecuting the purveyors of said treatments under existing laws).

    Nah, that's a common misconception. People have it in their head that a laser powerful enough to be considered a weapon would leave a neat little cauterized hole in a person.

You won't get a burn here, and perfectly undamaged skin an inch to the left. It could happen that way if the laser is tightly focused in order to leave a very small heat affected zone (important in some industrial applications), but I wouldn't bet on it even then. On a laser powerful enough to cut or weld, you'll get a wide circle of flesh damaged to an increasing degree as you near the center, a deep burn at the point of focus, and water at the wound site flash vaporized to steam, which may further aggravate the injury. Bleeding, and more importantly internal bleeding, may be present, and if the damaged area includes a major blood vessel, then you're about as screwed as if the damaged were caused by anything else.

Take an alkies booze away for a month, and he will suffer a breakdown, complete with DTs. Not a bad way to tell the two apart.

    Note the distinction here between inconvenience and withdrawal. The hard drinker will be inconvenienced by the lack of booze, which we're presuming he enjoys, and he'll respond to the lack with annoyance. The addict will undergo withdrawal, which has a concise, physiological definition, and is altogether a disproportionate response to the loss.

    Doesn't really work as a definition for "addicted". To provide a counter example, there are "high-functioning" alcoholics - just as fucked up as regular alkies, but able to hold it together enough to keep a job, maintain relationships (albeit often dysfunctional ones), etc. Often the shit hits the fan for them eventually, though this isn't guaranteed.

    A better defining question for addiction is: can you quit? The oft-modified joke "I can quit anytime I want, honest" has a grounding in reality. An addict would be very hard pressed to quit. Quitting would hurt too much. When they do ditch the thing to which they are addicted, they usually have to cut it out of their life altogether, and can't (safely) go back. As an added drawback, half the time "quitting" involves trading a crippling addiction for a less serious one.

    Time the delay between the first shot fired and the first puff of dust when it hits. Then, factor in the speed of the shell. Trust me, they're a ways off.

    And having not been on an apache airship I assume that they don't have to look through the shitty b/w camera. I also assume that there are multiple people in the heli which could look.

    Yes and no. Their optics are better than what you see in the video (it is, after all, youtube). They aren't that much better, however.

    Per the multiple people comment, if it was an Apache, and not an AC-130 as some have speculated, then there were no other people on board. The crew of an Apache consists of the pilot, and the gunner. And the pilot needs to, you know, pilot the heli, not look at the ground (hence the need for a gunner in the first place).

    I also assume that they could use shitty regular 10$ binoculars if they didn't feel like using their high quality army binoculars that i assume they have.

    Actually... no. Granted, they do have better binoculars than you can get for $10, but there isn't any secret high tech binoculars reserved for army use. Hell you wouldn't want ultra high tech ones anyway - you want something simple and reliable.

    But back on point, you're correct in that they did have a better view of the action than the people watching it on youtube. But their view wasn't as much better than you seem to think it was. Moreover, we have the luxury of pause and rewind, two things that make ID a hell of a lot easier than high resolution, not to even mention hindsight. We know the whole story, we can watch the event repeatedly, and pause to determine than no, that isn't a rocket launcher, it's a camera.

    I think all of these are fairly safe assumptions.

    I'd suggest doing a bit of research on the subject. Most of what you want to know isn't classified, hard to find, or particularly technical. You needn't take my word for any of this.

    I would agree that the gunner (and as far as I can tell, it was the gunner talking) was overeager. Where you and I disagree is the extent to which he had a better vantage point to determine who was armed. And since they'd been called in to look for someone who'd attacked a ground force in the vicinity, it isn't hard to imagine that, from a distance, they mistook the reporters for the people they were supposed to shoot.

    As I believe I've mentioned, the turning point from my view of things was firing on the van. Up to that point, it was a case of misidentification of camera carrying reporters and armed civilians for an actual threat. Once they had ground forces en route to mop up, they should have ceased fire and left the van alone. Firing on unarmed civilians giving medical aid to a wounded person is a big no-no.

In the latter case, the M230 can turn far enough to the left to allow the gunner to fire sideways like that, and the video is expressly identified as being from the gun-sight (meaning we don't see the direction of the aircraft's nose).

    As for why the designers don't include something smaller caliber for dealing with soft targets, that's probably mostly a weight restriction. More weapon systems would require displacing something else to maintain maneuverability. The existing weapons are overkill for soft targets, but the general attitude of the army is better overkill than underpowered.

    It's possible some people in the crowd were in fact armed with rifles. Hell, they may have been an armed escort, given that this was a war zone.

    Second on that. Firing on people you mistake for the enemy (and who look armed, might even have been armed) is understandable. Firing on a civilian vehicle trying to rescue the wounded is not. A better solution, given that they did have ground assets in the area at the time (as evidenced by the arrival of a group of IFVs shortly after the engagement) would have been to let the ground forces intercept the van. They have the option of stopping it without killing the people inside.

    Moreover, if you watch the video, it's pretty obvious that the people who get out of the van aren't armed.
