I didn't join any outcry after the killings in Littleton, but I'll state for the record that shooting people who are minding their own business is bad, including in Baptist churches.
I think we're unanimous that the large increase in the rate of violent crime during this century is a true problem with our culture (and that the more-or-less leveling off or even small decrease in the past decade is a good sign).
Of course, this subject is under intensive study. Which is not to say I know the answer. But it is to say that a Senate committee might not do anything useful. I can hardly see how even... well... how anyone could describe censorship as a "means of cultural renewal".
