Bad Genes and Bad Brains
Jul. 2nd, 2011 07:33 amIf you think genes don’t affect how people behave, consider this fact: if you are a carrier of a particular set of genes, the probability that you will commit a violent crime is four times as high as it would be if you lacked those genes. You’re three times as likely to commit robbery, five times as likely to commit aggravated assault, eight times as likely to be arrested for murder, and 13 times as likely to be arrested for a sexual offense. The overwhelming majority of prisoners carry these genes; 98.1 percent of death-row inmates do.

I am only excerpting the first part, describing some of the stranger case histories, including one notorious to these parts, the University of Texas Tower sniper, the Charles Whitman case.
