> I'm not sure what would need to happen to change this sentiment on a large enough scale to get people motivated into political action. A couple of razzias where they or their loved ones were taken to gas chambers should do the job. But we have such short memories. In just about every Dutch town, usually near the railway station there is a monument documenting just that and it still does not seem to make much of a d…
The Nazis didn't have anything like modern surveillance, and they didn't need it to enact the Holocaust. So I'm not sure what your point is; could you clarify? Surveillance enables many kinds of government oppression, but large-scale ethnic cleansing doesn't seem to be one of them, in that it's already possible and efficient. The Nazi's logistical problems in enacting the Holocaust were more in moving and killing Jew…
If they had there would most likely not be a Jewish people to speak of, as it was the little bit of automation they had coupled with a stereotypical dose of German thorougness already did a very good job (good is not really applicable here). Now combine that with say a twist of 'big data' and some nice pattern recognition algorithms (facial recognition for instance, or maybe DNA analysis) and it would have been possible to round up a significantly larger chunk of the Jewish population than what already happened.
The fact that we now have wall penetrating radar doesn't help either.
> The Nazi's logistical problems in enacting the Holocaust were more in moving and killing Jews, less in finding them.
They had a hard time actually, because the local population did a reasonably good job of hiding them in the strangest spots.
> Surveillance enables many kinds of government oppression, but large-scale ethnic cleansing doesn't seem to be one of them, in that it's already possible and efficient.
Yes. But it won't be made any less efficient by all this helpful identification technology we have nowadays, most likely more, and communications intercepted long before a conflict might even help to identify those that would aid the hunted.
