I'm wondering how much damage a guy like this could do in the future if he decided to kill as many people as possible. I figured that some readers would have a strong enough life science background to be able to make a reasonable estimate.
This is assuming that his goal is just to kill as many people as possible. He could much more easily have set up some kind of bomb in the movie theater and killed as many, if not more, people. My impression is that he wanted the visceral rush of murdering all of those people first-person.
A Ph.D student in neuroscience shot at least 50 people at a showing of the new Batman movie. He also appears to have released some kind of gas from a canister. Because of his educational background this person almost certainly knows a lot about molecular biology. How long will it be (if ever) before a typical bio-science Ph.D will have the capacity to kill, say,a million people?
Edit: I'm not claiming that this event should cause a fully informed person to update on anything. Rather I was hoping that readers of this blog with strong life-science backgrounds could provide information that would help me and other interested readers assess the probability of future risks. Since this blog often deals with catastrophic risks and the social harms of irrationality and given that the events I described will likely dominate the U.S. news media for a few days I thought my question worth asking. Given the post's Karma rating (currently -4), however, I will update my beliefs about what constitutes an appropriate discussion post.
