They aren't blaming the victim, they are too stupid to realise that wrongful conviction means that the convicted didn't do the crime. They think that they were convicted for a wrongful action aka they were guilty.
Victim blaming no. Dumb beyond remedy, yeah.
That includes OP and other comments here that also misinterpreted their comment confidently though. Like, read the title, that's not what they said at all.
Luckily the one that responded them corrected them, but if instead of being educated they received the hate from these comments they'd go way crazier.
Edit: idk why I assumed the comment was from a woman, I'm sorry. I changed all pronouns to they/them.
