I have a personal theory about PTSD I don't talk about because I could be wrong. Those with a conscience-empathy suffer from PTSD and those without a conscience/empathy, glory in not having variable degrees of ptsd. The more sociopathology the less prone people are to have recurrent PTSD.
There it is, but like I say I could be wrong.
A second Capitol policeman who fought on Jan. 6th has committed suicide this month. Perhaps other factors are more important.
