Quote from prosecutor's FB according to this blog post: “I’m trying to get home for the past two hours, but I can’t because there’s some protesters blocking off traffic […] please, somebody tell the police that this area is under the jurisdiction of my court and, if any of them kill a protester, I’ll just archive the case”.
Scary!
It's a little more than just an humorous remark (EDIT: not that I'm assuming he would actually archive the cases); the original text seems much more hateful. The last part of the post is roughly:
Shitty petistas¹. Motherfuckers. (...) I miss the time when this kind of thing was resolved with rubber (sticks) on the backs of the cowards...
¹ Supporters of the Partido Trabalhista, as far as I can tell.
>"there are certain positions of power from which I do not appreciate joking."
Exactly how I feel.
And no way it was a joke, since he used bad words in the original post I haven't translated, which indicates he was really pissed off and writing fluently.
