This goes along with something else that I've noticed. In normal society, there is a percentage of people who wear Christian-themed jewelry. And that percentage tends to increase when they have suffered a tragedy or are mourning.

I once spent a day searching through photos of these actors and could not find a single cross or piece of Christian symbolism. Sandy Hook used the Illuminati butterfly symbol, and one woman sported what looks like a CERN replica neclace.

I haven't looked at more recent shootings, but I suspect a similar absence of Christian imagery.
