Things look quite different from Moscow. Russian media are hell bent to prove that it was ukrainians that shot the plane down. Main arguments are that rebels don't have SAMs for this and
ukranians did the same in 2001. It also should be noted, that Ukrainians
were in denial for 8 days in 2001 and declined Russia's claims (which were eventually proven truth). Russians are claiming that rebel's BUK, shown in various pictures and videos, was not functioning. An army expert on TV defied Obama's statements that the missile was fired from rebel's territory, as he claimed that US satellite precision rate is not good enough to determine this.
Today a taxi driver asked me "Haven't you heard, those damn ukrainians shot down a civilian jet". I won't generalize one man into the whole nation, but the majority of Russians seem to think that it is ukrainians who did it.
