Vicious cycles

This is a fascinating read.
Dr. Dorothy Lewis of Yale University has studied killers her whole professional life. Some are famous, others not-so. She calls the violence they enact a public health crisis. As such, she takes a prevention approach to her work. Based on her studies and interviews, murderers typically have been abused themselves. The abuse not only teaches them to deal with problems with violence but the abuse actually affects their brain.
No matter how you feel about capital punishment, you have to know that prevention would keep more people out of prison, and keep more people alive. In Dr. Lewis' dreams, she would want to work with the families of child-abuse victims instead of working with the defense team, as she typically does, when it's arguably too late.
