QUOTABLE: Mary Ellen O'Toole

"Most state parole boards do not use... recognized tests to determine if an inmate is a psychopath before they vote to release an offender. [FBI special agent Mary Ellen] O'Toole says it's only a matter of time until a psychopath commits a new crime.

"'It's a very short period of time before he or she will re-offend and re-offend in a violent way. Some of the current research indicates that psychopathic sex offenders who undergo prison treatment programs are actually worse when they are released,' she says.

"Psychopaths can learn how to perfect their crimes from prison therapy programs, says O'Toole. 'Psychopathy is a personality disorder. It does not lend itself to treatment or to rehabilitation. So if you think you can help someone become a non-psychopath that's very naive.'"
