I'm not saying we should be entirely complacent, but the response from the western world since 9/11, and ongoing, has been insane, and has caused more civilian deaths than any terrorist attack could ever cause.
Devices like this, or indeed body scanners, just add to the security theatre that makes corporations money and allows our politicians to further continue the narrative of fear that allows them to get away with almost anything.
Sure, but let's say we take the "stop freaking out about it" approach and it enables further mobilization. Suddenly those things change in a hurry.
> The idea of terrorists getting hold of a nuke and actually being able to use it effectively is, frankly, ridiculous.
Unless a terrorist organization is able to morph into a pseudo-state. Which sounds a little less ridiculous than it did five years ago.
The point is primarily that chastising fear/effort/resources/counterattacks based only on the current statistical threat level is short-sighted.
