Some people here raise good points, but what little is cited from the study isn't enough by itself to pass judgment on what was written by the Harvard author. It might be useful to support your position if you are already decided, but to somebody coming new to the argument there isn't enough quoted to judge the study. The final part of the quote discusses onus, not facts. That sounds like more a philosophical debate than a scientific debate. The guns versus crime question depends on many more inputs than are mentioned above. Pure numbers won't answer the question one way or the other, IMO.
