In order to take a stand while talking about this topic, I believe that first, we need to decide on one, particular definition of vigilance.Let's say this one:
Vigilance (ˈvɪdʒ ə ləns)
n. the state or quality of being vigilant; watchfulness.
So, to be vigilant means to be watchful and observant. How does it translate to the way governments can utilize this value?
The first thing which comes to my mind is monitoring citizens. There's a word in English - invigilation which is sometimes used in discussions on very similar topics to the one we're talking about at the moment. What is more, it comes from vigilance itself! It means to watch somebody very carefully, so they wouldn't be able to cheat. Therefore, What if we applied this definition to the way countries are being governed?
From my point of view, it would mean watching every step of all citizens in order to determine who is likely to comming a fellany, even though they didn't really do that. It means, that algorythms and machines would probably calculate the probabilities based on data gathered by the system. Even if we employed people to go through it, who would they be to decide who will and who won't commit a crime? How can we constrain somebody who hasn't done anything yet? I think it's a road leading to totalitarian regime at best, because it gives the government a way, to control all citizens in their country directly.
To sum up, I not only not see the so-called vigilance as an aim to governing a country, I see it as a threat to freedom, every single person living in any country is entitled to.
