Two years ago, almost to the day:

"Following the 2012 massacre at Sandy Hook Elementary School, then-Newtown police Chief Michael Kehoe asked federal agencies to help prepare a road map for how departments across the country should handle the aftermath of a mass shooting....The report...includes a three-page letter from Lori Kehoe...who wrote about how one of her husband's biggest fears was that some Newtown officers would kill themselves..."

Let's get real here. PTSD suicides are largely the result of guilt--not simple witnessing of death. Iraq vets kill themselves over guilt for taking civilian lives (ask them), not random PTSD over operations against other gun-wielding combatants.

In what other tragedy in the years before or after Sandy Hook has the primary worry been that the responding officers might later commit suicide?

I don't blame the chief one bit for worrying that his men might commit suicide. That admission on his part, however, is a startling Freudian.

Why would NPD officers feel so much guilt after Sandy Hook that they might become suicidal? We've already determined why. No good comes of the fraying attempt to suppress the truth.
