No you said 'Most people posting here would be astounded to discover that they could be classed a criminal or terrorist, ' which is clearly bollocks without evidence so I'm wondering why you would think it?
You are conflating two answers I gave.
I asserted that anyone of us here could be deemed a criminal or terrorist, since those two things are just what the law says they are (which is a counter to the "criminals don't deserve human rights" meme). In such instances, there would be evidence - whatever the law required to make you guilty in the first place, but there would be evidence.
Another poster then said they were quite happy to have people locked up before they commit a crime. In that instance, I was taking the liberty of deducing that people who haven't committed a crime will have no evidence against them (evidence of what , one asks ?) and pointing out that a regime like that is open to all sorts of abuses. Especially when people twig that the simplest way to deal with people we don't like is to "report" them as "possible terrorists".
As far as I am aware, none of us on this thread has committed a crime. But any of us could. Using the logic that we should lock people up before they commit a crime, means we would all be at risk of being in jail.
For nothing.
One thing this thread does demonstrate - in a bitter sweet way - is how well our Human Rights serve us that we can take them for granted or think they are a "nice to have". There are many places around the world where that isn't the case, and invariably they are not very nice places at all. China and North Korea spring to mind.
Any US schoolkid would be able to quite the various bon mots of the Founding Fathers. In this case the comment that those that sacrifice liberty for security will enjoy neither seems apposite. (I think it was either Ben Franklin or Thomas Jefferson).
