This is a PTSD technique used by a colleague of mine from Detroit, Michigan using a work of art from Francisco Goya found in Museo del Prado in Spain. I have seen this work of art live a couple of times in Madrid and never would have made the connection LaMaurice did:
Police Psychology: The Folly of Fear
LaMaurice H. Gardner, Psy.D.

This is a picture called the Folly of Fear. Now in the background of the picture (in the past) you can see Spanish soldiers engaged in combat. They are beside the tree fighting for their lives. You can see the front of a cannon just to the left of the left most figure. They are at war.
Now, in the foreground of the picture (in the present) you can see these same Spanish soldiers. What are they being confronted by? What is that standing over them?
“A Ghost.” (grim reaper, death, etc.)
Yes. And what is a Ghost…. a Ghost is a memory from the past. (more…)
Thin Blue Mind / Smokey Heroes

nights of drinking, camaraderie and debauchery. They would get drunk, be obnoxious to regular citizens and have sex with a variety of barmaids, hookers and naïve young girls wanting to have a good time. During the day, they would shoot gays in the park and bond together so nobody could get the real story and no cop could get charged. Their pranks on each other are so appalling and dangerous that Joseph Wambaugh actually had his name taken off the film. Superiors are all jerks, judges are listed as “black-robed pussies.” It was called a “film about brutes for brutes.” But the book and movie actually started something that is quoted frequently today, and perhaps is part of the way the public views cops.
