Surely you jest, bob. It is true in UK they do more surveillance than we do here in North America (they have cameras at many traffic junctions for instance).
I don't jest, I know too many retired British cops who have moved here who can attest to this because they were part of the system. I don't know who the "they" are you refer to, if it is the UK, well, they have surveillance
everywhere. As one fellow said to me, "you, on average, cannot go 400 metres
anywhere in the UK without being photographed".
Terrorism is a handy excuse to suspend or eliminate freedoms. Sure surveillance may deter some random crime but doesn't stop terrorism, it only provides evidence in the aftermath, the victims are just as dead. Not only that but he British rendered its populace defenseless, they also outlaw self defense, even in your own home.
As for security, it was the States' lax security measures that allowed 9-11 to happen, and trust me, they were lax and targetted the wrong people. The same is still happening, here and abroad. Extraordinary security measures are merely window dressing and optics. A false sense of security is a dangerous thing, and that security becomes out last line of defense. At least now, in the US and Israel anyway, the last line of defense is armed pilots.
Right to safety comes before everything else.
We have no such right. Believing so is dangerous because the state will put our safety in the hands of the state by eliminating out freedoms in the name of safety, safety they know is impossible to provide.
