Imagine this....
Said spy uncovers a plot to nuke a city. The only way to prevent this from happening is by killing the terrorist who is carrying the nuke into the heart of the city. If the spy does not act immediately, millions of innocent people will die.
Scenarios like this are more fantastic than warp drive.
Science and technology have discovered and done the most amazing things that seemed to be impossible, that there is a smidgen of doubt about lots and lots of scifi improbabilities. That's all a willing suspension of disbelief needs.
But crap like the scenario above? Experience tells us this is empty rhetoric, fantastic hyperbole meant to rig discussion by posing a false either/or.
Humbug.
