Normally, you expect that when someone is acquitted of a crime, the government does not punish them for it. But not, apparently, in the UK. An Iraqi man accused of making a video identifying potential terrorist targets will apparently be subjectd to a control order - despite being acquitted on all charges by a jury. This goes beyond double jeopardy to strike at the very heart of justice itself: the man has been found innocent, but will be treated by the government as if he is guilty regardless.
Really, if they're going to behave like this, you wonder why they even bothered with the pretence of a trial at all.
