Maybe, though it will be awhile.
Let’s talk about voltage spikes emitted from brain tissue and picked up by some type of encephalograph. Brain spikes emitted after watching some type of external video, pictures, scenes of sadism, rape, etc. I would be really interested in knowing why that was interesting to the person whose brain emitted those spikes.
Maybe this is a way to identify serial shooters, child and women or men killers. I am sure others forms of “testing” would corroborate the encephalographic spikes.
