Still not seeing any proof of US lying. Wonder why? Oh right, that's because there is none.
Quote me where I say US is lying?
But Butan Putin and the Kremlin are directly responsible for this because they are destabilizing Ukraine and have provide the expertise if not the manpower to make the shoot down possible. Putin doesn't have to push the button himself to be held culpable. Just like a Mafia Don, he is held responsible for the actions of his hit men. And to say this is so is not a falsehood.
You seem to be saying that the US is holding back some information that could refute that Russia is responsible for this.
I'm not debating the truth of the claims, only showing that the claims do exist to you and those who do not believe, or pretend to not.
Claim: US officials never told anything else than "missile came from separatist area" ?
Reality: they claimed more than that, for examples that Russia was directly or indirectly responsible.
(one) Proof:

A relatively minor error that doesnt deserve as much posts, so I will end my case here.US did claim a lot more than the fired missile exact origin.
In the few first days, they even thought that Russia directly fired the missile, but some more time later,
their own intelligence reports diverted from this version, by going backward and taking more caution in their accusations, at which point they said what you're trying to say : Russia is backing them, arming them, helping them, so they are responsible for what happened. This is not new, everyone have already accepted the possibility in this topic that it is true.
