In Germany it has been the rule for years - first implicitly in the Volkszählungsurteil from 1983 [1], then explicitly [2] - that indiscriminate camera surveillance of demonstrations or police controls that register names creates a "chilling effect" on the right of people to free assembly.
The "convincing case" is China's "social credit" system and the numerous abuses of subpoenas for dragnet surveillance in the US. In Germany, back from the IP address collection debate over a decade ago, we have the saying "Wo ein Trog ist kommen die Schweine" [3] - where there's a feeding trough, pigs will come on their own.
