This is from EvolutionistX (good article, by the way).
“Not retarded per se. My personal experience is most criminals stopped developing emotionally at about 3 or 4. They live life for the moment, think only of themselves, have no impulse control, can’t control their emotions, throw temper tantrums when they don’t get their way, can’t think past the next 10 minutes, don’t understand consequence, etc…… They are basically little children in adult bodies. Of course, most 3 or 4 year olds are better behaved than the average criminal, but you get the point.”
“I found that better than 90% of them were functionally illiterate, so when they say reading is fundamental, they aren’t kidding!”
