Here in Argentina if you piss off somebody probably you will be found dead in a suspicious way.

One of the most recent cases is the federal prosecutor Alberto Nisman[0], who accused the president Cristina Fernandez de Kirchner, among other politicians of exchanging alleged Iran terrorists for deals. Nisman was found dead in his house a day before going to talk to the Congress about his findings.

Some other cases: Lourdes Di Natale, a key witness (it was the secretary of Emir Yoma, a presidential advisor) in a case of the government illegally selling weapons to Ecuador, "felt from her balcony" before going to testify. Also, to erase evidence in the illegal arms case[1], they make to explode a militar arms factory in Rio Cuarto, Córdoba, causing 7 deaths[2]. By the way, only two people were found guilty of the whole investigation, one is the former president Carlos Menem, but because he is currently a senator he can't go to jail until the senate makes an special session to make that happen, which is unlikely.

Julio Lopez, a witness that "disappeared" before testifying about how he was disappeared and tortured during the last military government[3]. Probably this time somebody finished the job.

And the assassins are almost never get a sentence because the justice is so slow, inefficient and corrupt that very few cases are resolved. 21 years after the AMIA attack (a car bombing of the Jewish center in Buenos Aires, which killed 85 people[4]), they didn't find any guilty yet, and many evidence just got destroyed because they leave it outside instead of keeping it safe.

Also, there are cases like José Luis Cabezas[5], a photographer that took one of the few pictures of a gangster, was killed a year later taking that picture, and because the people was extremely pissed off about that case, with an obvious mafia touch, the justice moved fast and found the band contracted to kill the photojournalist (one of them was a policeman and inspector), but because our laws, almost all of the assassins are free today because legal reason (one of them are was working as private security some years ago).

Let's also talk about the prison system in Argentina. In the mid-70s, because jails were so populated, they had the idea that instead of having several cells for prisoners, they could break the wall and have a hallway. That way it is not so obvious how many prisoners they can put there. I'm not sure if "all prisons in Argentina" are like this, but I read that the one in Villa Devoto is like that[6].

Prisoners are not provided with clothes or beds, they sleep in mattresses in the floor. Most of them are raped, and some get HIV.

So here we are at another level. Here there are no so many companies worried about someone getting in their way of making money or military power going to kill someone that their consider a threat.

Here the power is very concentrated in politicians and some few businessmen/gangsters that are going to kill you if you get in their way. It is not really about "free thinking", it's about "your idea/information is going to affect my situation". Probably always has been like that.
