Kaczynski

Because, of course, red-blooded, white-skinned folks like Timothy McVeigh, Ted Kaczynski, and Adam Lanza pose no threat at all.

In terms of individuals, I have found Andrew Kaczynski from BuzzFeed to be a de facto post-disaster photo legitimizer.

Ted Kaczynski, the Unabomber, had a low resting heart rate at 54 beats per minute.

It took 18 years to catch Ted Kaczynski, the Unabomber, and seven to catch Eric Rudolph, the Olympic Park bomber.
