20 years ago are not that long ago, neither 30, also the police does massive profiling during protests, I've had plenty of friends being profiled (pictures + videos + cross checks) during mild protests just because they were waivings signs.

let me rephrase, the italian police does actively get your pictures, cross checks you, and do a profile about you without even being recognized as a previously person of interest to law enforcement

1) The other examples in the same comment are more recent.

2) What happened there was so bad Italy was found in violation of ECHR. That nothing has substantially changed is in and of itself a major part of the problem.
