Well this one has really rattled the country. And if my 6th sense is not incorrect it's not just on the radio or in the newspaper. People's demeanor is a little different, traffic seemed to be a little less aggressive, the kid at the deli actually said "how ya doin' today." This one has slowed people down and humbled them, I think.
I've been reading various analyses and this one really is a microcosm of literally all the big things going on today. In terms of symbolism, this is up there w/ 9/11, maybe even exceeds it. That's what has people rattled - the symbolism. Symbolic Exchange and Death.
