“After the slaughter of nine worshipers at a South Carolina church last June, but before the massacre of eight students and a teacher at an Oregon community college in October, there was a shooting that the police here have labeled Incident 159022597.01. It happened on a clear Friday night at an Elks Lodge, on a modest block of clapboard houses northeast of this city’s hilly downtown. Unlike the butchery that bookended it, it merited no presidential statements, no saturation television coverage.”
