I think Jay Carney might be right that today might not be the day to debate policy proposals, specifically gun control. But I think people who react to that statement by saying if not today, then when?--are also right.
We have a problem, and we need to try to fix it. We need to have a real dialogue about the culture of violence in this country and what we can do about it. We don't need the kind of debate where one person's suggestion is only met by somebody else pointing out what is wrong with that suggestion. Those kinds of debates are themselves symptomatic of the culture of violence we live in. Instead, we need to listen carefully to all legitimate ideas about how to reduce violence, and think about steps we can take to reduce the occurrence of these kinds of tragedies.
