This week brought powerful reminders of what happens when a government fails its citizens. On Wednesday, as the nation continued to mark the 10th anniversary of Hurricane Katrina's unnecessarily tragic destruction of a uniquely American city, the nation woke to yet another uniquely American tragedy, as two Roanoke-based news staffers -- reporter Alison Parker, and cameraman Adam Ward -- were gunned down on live television. It was the beginning of a news cycle we know all too well: shock, outrage, calls for sensible guns laws, and then, if past is prologue, nothing. Since the Newtown shootings in 2012, nearly 85,000 Americans have been killed by guns -- yet common sense gun legislation proposed at the time by President Obama continues to languish. On Thursday, the president called Katrina "a man-made disaster, a failure of government to look out for its own citizens." The same could be said of Roanoke.
