The BBC reports Facebook has lifted a blanket ban on beheading videos the company introduced back in May.
Here's a company spokesman:
"Facebook has long been a place where people turn to share their experiences, particularly when they're connected to controversial events on the ground, such as human rights abuses, acts of terrorism and other violent events."
The specific video in question purports to show a masked Mexican man killing a woman. Facebook's is allowing it to be posted because people are sharing the video to condemn it. Facebook says that they would consider censoring clips like these if they celebrated violence.
I've never really been able to stand watching these kinds of clips, so I don't. But if sharing them might spur people to some kind of political action that could stop actual, real life beheadings from happening, that seems worthwhile. The BBC has a quote parade of folks who worry about the psychological damage these clips will do to them or to their children. The obvious response? Just don't look.
