Major social media network Facebook is again allowing users to post videos of people being murdered.

Facebook reversed an earlier decision banning posting of videos that showed people being beheaded or killed but now allow the videos with a warning that the video contains graphic content. The initial ban had been made after outcry from worldwide government officials.

The majority of the videos are of the beheadings of members of Mexican drug cartels. The videos usually show the entire murder from start to finish. The site is also allowing the posting of executions taking place in the middle east and Asia along with terrorist killings.

Those taking the social media giant to task say that because the site allows users as young as 13 years old the videos could cause significant mental stress. The critics point out that Facebook has rules prohibiting videos that show a single woman’s exposed breast – thus blocking some videos of mothers breastfeeding their children – but have nothing to stop what are essentially snuff films.

Facebook says they are allowing the videos to be posted so that users can discuss them and share their outrage about the killings. The site says they will remove videos if the people who post it glorify the violence in the videos in any way.

British Prime Minister David Cameron called out Facebook saying their actions were irresponsible and that they “must explain their actions to worried parents.”

Facebook has not commented about the decision to add warnings to the videos.
