I guess some people are surprised police might get involved in a defamation case because in the US it's not a crime but a civil wrong? Which means you can't get help from the police to identify the person who made a defamatory tweet? Or something?
Also, if someone says something that could threaten my safety (either directly or through inciting others) I would very much like them to get a visit from the police. This situation is so easily avoided by not being a dick to people.
Yeah, if you are from The Netherlands and want police showing up your door, mention on Twitter that you want to shoot mr. Wilders. Threatening someone to take away their life has repercussions. How peculiar!
(Please don't do it. Example is just illustrative. Actually, I know a website with a forum where this happened approx 20 years ago. Server got seized. They didn't log. FDE, but obviously got broken at some point.)
Freedom of speech isn't that you can spout whatever you want and not face repercussions.
Besides that, there's Popper.
Furthermore, there's this thing called chilling effect. You might wanna ask GOP Senators and Congressman about that.
I have faith in LLMs and AI, as long as it is reproducible and transparent. Right now, when I use Mistral, it refers to sources. A step in the right direction.
