It's a propanganda channel. That's obvious, right?
First off, the footage they claimed the BBC invented, I've never seen, and doesn't look much like BBC footage in any case. It looks like something from a daytime soap. What it does resemble, slightly, is Syrian state television, which occasionally gets clips shown over here in segments like 'meanwhile the Syria state television is saying X'
Second the allegations that they're making didn't get much play over here. There have been comments about possible chemical weapon use but they don't match what RT is claiming was faked, haven't had much stir over here, and they certainly weren't used as the justification for any kind of action.
Thirdly, they cite George Galloway MP for coroboration, but the clip of him supposedly commenting on their allegations is very vague. It took me a while to work out why, but then I realised they'd just copied an anti-government speech from the Iraq war and pretended it was current and about Syria. Alert observers may notice that he referrs to the Bush-Blair war machine, despite neither leader still being in power.
Fourthly, the criticisms they make don't seem to stand up to even casual scruntiny. For example they complain about the BBC citing information on casualities from the 'Syrian Obervatory on Human Rights', saying it's not a credible source. Well, sure, it probably isn't, which is why the BBC reported it as a claim from the organisation, rather than a fact. Since the webpage is still up, you can see for yourself whether the BBC was basing their report around this source. I don't see that they are.

Fifthly there seems to be quite a gap between the claims made by the presenter, and the evidence presented on the screen. The interview with a professor from the university of illinois doesn't match the commentary given about what he's saying, several of the statistics were simply listing how many sources disagreed with RT (almost all of them), and there's lots of juxtapostion of the word 'lie', people in authoritarian looking riot gear, and discussion of government conspiracy with western journalists giving reports, but nowhere do the reports shown actually back up the commentary about them.
Sixthly, RT can't make up their minds what they're saying. They claim that news organisations are infiltrated by the CIA in secret, that these organisations are forced to have CIA members on staff (so, not secret), that ordinary journalists on location have their orders as to what picture to encourage, and that news stories are fabricated using actors. Try and imagine a organisation where all of these are true for a moment...
In other words, it's pretty childish propaganda. Like most of RT's output, it's designed to impress people who don't look or listen too hard at what's actually being presented, and a few minutes of research demolishes most of what they say.
I've no doubt that there is a problem with bias and interference in media organisations. But this kind of cartoon clumsy capering is not it.
