Others besides Infocult have been pondering this cannibalism wave. Here are some samples.
- Jr Deputy Account assembles a zombie/cannibal attack timeline dating back to 2008. Although he focuses on US evidence, the sheer amount makes him wonder "what in the name of sweet baby Jesus is happening here?"
- New York Magazine builds another timeline, limited to the past year. Nice conclusion: "In a weird way, it's kind of a relief... People actually eat other people all the time! Of course, the bad news is that people eat other people all the time." [italics in original]
- The Examinar offers an even shorter timeline. No theories.
