A lot of people seem to believe that it is bad form to talk about the factors that enabled a tragedy while a tragedy is still fresh in people's minds — that it is somehow uncouth or opportunistic. If there is a mass shooting, or a toxic spill, or a case of clergy sexual abuse, many think that is "not the right time" to talk about those issues; that we are somehow disrespecting the victims rather than honoring them.
I, for one, look forward to a day when it's OK to talk about these issues. Not just because we might, at last, be able to find ways to address these horrors, but because it means that there would be a single day in which an innocent is not killed because a purchase of deadly weapons was not adequately monitored; a day in which people's health and livelihoods are not destroyed by casual treatment of poisons; a day in which a child is not held down and raped by a man telling the child that he is doing god's work. That day won't solve the problems forever, but it would be a welcome change.
