This answer is going to be a very personal answer from experience. The common characteristics I have found in my teaching in both juvenile and adult corrections, and in being an on-call crisis counselor for a county jail, several characteristics are common to all. The inability to recognize or Admit that they have or there is a problem is paramount. Whether it is untreated or undiagnosed mental health issues such as depression, bi-polar, schizophrenia or behaviorial problems such as pedophilia, criminal sexual conduct, white collar crime stealing or embezzling, very few of the people see or admit their problems. Seeking help or admitting a need for help in any way is another as they view seeking help as weakness. The traditional strong versus the perceived weak or the predator instinct is another also. Unable or unwilling to see how they act as a predator allows them to continue the behavior. Cleverness or the "god" complex is another as the risks taken are enormous while they feel invincible. The white collar crime in this country costs the taxpayer billions; however, while white collar criminals hurt many more people, they are seldom punished in the same way with the help of money and good lawyers. One need only look at the banking industry or the money/stock market frauds to see the differences. I realize that this answer may not be what you need as this is more personal observation, and does not address every criminal justice agency.
