Facebook butchered (pun intended) a case where cartel sicarios executed a Mexican national, but before they finished him off they tortured his Facebook password out of him.

They proceeded to send members of his extended family, his friends, and family members' friends taunting messages from his account, which by this time had his profile picture replaced with a photo of his decapitated body with his head and genitals essentially co-located in an obscene manner. The other pics on the account (background/header image, photos of the decedent, etc.) were replaced with photos of the victim in various stages of torture & dismemberment. I saw them and it was horrific (and I'm pretty jaded).

FB slowly responded and locked the account, except they left his profile picture alone (beheaded body) and didn't delete the messages that had been sent. It was just a trainwreck, but who cares? They're just Mexicans and they don't know any politicians so... /s

Atrocious behavior, and I saw it for myself on FB after seeing screencaps so I know it wasn't fabricated. I hope they can find a way to better handle this stuff. It makes revenge porn seem mild.
