He beat a civil defamation suit; these cops still know where he lives. Do you think the events of today made them less angry at him?
In what other countries could one publicly shame the authorities this severely? I think that's what was meant here.
And yes, it's great.
Not quite sure which part of this process do you think is even remotely unique to the US.
In the US, the plaintiff needs to prove, to a preponderance of evidence, that the statements were false, intended to be perceived as statements of fact, harmful, and that there was negligence or actual malice in the defendant's belief in those statements.
A bunch of European countries allow defamation cases despite the statements being true. Belgium, Finland, France, Germany, Italy, Poland, Sweden, Switzerland, and The U.K definitely fall into that category (though in some cases like the U.K., truth is a defense if the plaintiff can prove the statements were in the public interest).
To people outside of Europe, any category of countries that includes the U.K, France, and Germany can colloquially be referred to as "Europe" pretty comfortably.
If you really want to generalise across the continent, the most common scenario would be that you're completely within your right to film them and publish that, but then the cops would argue (using GDPR of all things) that you have to blur their faces and names before publishing. (Try to argue != succeeding automatically, that's up to the court to decide.)
