Re: They've got you...
They'd just redefine "transmit" to make sure they got you, much as when many people are charged with "making" indecent images of children, what they've actually done is viewed it on their computer, thereby causing it to be downloaded and so a new copy "made."
My cynical mind suspects there are a couple of reasons for this. Firstly, it enables a longer penalty without changing the law (though that shouldn't be hard to do, even without whipping up a moral panic first). Secondly, when you hear about people being arrested for "making" doesn't it sound so much more impressive? It's as if they've actually tracked down and found the people physically abusing.
I'm sure, in a similar vein, they could find a learned friend who would argue that, for instance, the transmission of the video across the internet occurred as a result of you clicking on a link. Having established causality, it's merely a short leap to that that you, therefore, transmitted the video.
Few people with any sense of how technology works would necessarily agree with you, but the PR team would get to trumpet another terrorist suspect banged up, and everyone goes to bed feeling a little bit safer.
