My condolences go out to all of those who were affected by the recent Connecticut tragedy, and the recent Chinese tragedy. Of course, most Americans (particularly the ones sharing their opinions about gun control on Facebook) will pay no mention to the latter tragedy (I apologize for being in a rather cynical mood this morning).
Anyway, here are several thoughts that I’ve had related to the two tragedies.
1) Heinous crimes happen even without guns. 
2) Accidents happen and gun accidents happen. Accidental deaths, however, are a silly reason to ban something. Fact: almost three times as many children drown in bathtubs than die from accidental gun deaths. Should we outlaw bathtubs too? 
3) Hypothesis: We’d save more lives in this country by getting rid of McDonalds than we would by getting rid of guns. (HT: Guru Anaerobic).
4) If legally registered guns are the problem, why do we see so few murders at shooting ranges? (Hint: Legal gun owners aren’t the problem.)
5) It appears the American killer was also autistic, are we going to blame guns and Autism, or just guns?
6) I wrote a piece called “Guns & Epistemology” on Rationally Speaking after the Aurora massacre that seems relevant to share. 
The commonality behind all massacres is that the individual committing the crime against humanity was mentally ill. It’s easy to blame guns for the problem, but we ought to focus on the real issue here which is how we deal with mentally ill people. Of course, many people often use times of tragedy to create an emotional case for their irrational beliefs (there’s that cynicism thing again).
