So I think for a lot of folks Guantanamo does ring a fairly loud bell.
Here's a wee anecdote. When I was in my teens and early twenties (read that as late 80's) I was an active member of CND, the SNP and Scotland Out of NATO. I was active in the NUS (National Union of Students) as well and even organised a protest and student strike at my Scottish shithole of a college in Perth - having managed to drum up around 400 students to march upon the Tory offices in Perth to demonstrate against cuts to student grants and burseries.
During this time I was never arrested or apprehended by the Police. In fact I've never been arrested or apprehended and as far as I know don't have a criminal or civil violation record (except maybe a handful of traffic violations - speeding, and a driving without due care and attention when I was 26 [reading my map]).
After I left college, and despite being qualified for many jobs, the interviews came and went over around 6-7 years and I wondered why? Until it came to light there was an organisation called the Economic League which manually compiled lists of UK activists and fed them to many organisations as a form of blacklisting.
Whilst I was never able to establish that I might have been on their list, I had a fairly strong suspicion, with hindsight, I was listed. There's no way that the sort of jobs I was applying for, where right up until the last minute, the offers were withdrawn with no explanation.
Contrast that with the standard European model of criminal jurisprudence, in which the judge deciding the case is frequently also the prosecutor, and there is no panel of jurors, and no threshold of proof.
And what are you even talking about?
