Texas Murders
Some enlightening behavioral indicators on the late Texas church murderer:
The murderer "preached atheism"
The murderer had been "accused of domestic abuse."
The murderer was an animal abuser; had been "arrested for animal cruelty."
The murderer had been "dishonorably discharged from the military."
The murderer "had been denied a Texas Concealed Carry Permit."
The murderer "worked as a security guard"
There are probably more indicators that we don't know about yet, but these taken as a whole, scream sociopathy.
It would not surprise me to hear that this guy was a moderate to heavy marijuana user, which could explain why he spent time living in Colorado. Marijuana use is a trigger that has been directly linked to sociopathic and psychopathic behavior; the post-mortem toxicology should answer that question.
For anyone with at least a normal IQ, there should not be any doubt left in their mind as to what it takes to stop one of these renegade's. It's just too bad that there wasn't a trained armed responder, or two, serving as ushers in the church that day.
Hard lessons learned the hard way...
I suspect from now on, anyone walking around a church service wearing body armor might well be spending the night on a stainless steel table.
Remedial action for this type of threat should include a formal training program. For example, the successful FASTER program, that is presently geared primarily for schools, could be easily adapted to church's.
