Of course the attempted assassination of a major political figure is a big deal, but in a world of near-daily mass shootings it isn't as big of a deal as it might have been once upon a time. Remember when that guy opened fire on a congressional baseball game almost killing dozens? You barely do!
There's nothing these people want more than to hold solemn roundtables about the yearning for "national unity" or some shit despite, well, the reality of everything!
