Oh, like this doesn’t happen in the good old US of A!
Get real.
This is how the noose tightens. Every limit on freedom is justified as being neccesary for “national security”. The assault has already started big time - 9/11 gives them all the justification they need, and the public support to do it as well.
The main difference between the US and the UK is that Americans still cling to this idea that they are citizens.
