Rough Crowd

I gave my talk on "Video Games, Violence, and Crime" at the ZEW yesterday. I got lots of comments and questions about my data and methods. Most indicate little things I should have done or I could do further. But some of them could be quite damning to the whole enterprise. By the end, even I was starting to lose doubt in my results. By far, these were the best comments I have ever got on this paper. This is what research is all about. Thank you very much.
