If you find this era interesting, I recently read the book "
Burning down the Haus"[0]. Most histories I've read of the region and era focus a lot on the mechanics or politics of it, but the book was interesting to me in that it made you aware of the changes, the ebbs and flows of the East German security-state over time as they fought against even harmless "dissidents" and the abuses (and to a lesser extent incentives) to address those. Now I'm not bleeding-heart, but a lot of the tactics really start to look familiar. Modern America isn't that far removed from the Stasi.
