I taught at the FBI for four decades - how to think outside of the box and deal with social engineering.
I'm a true believer that you have a moral obligation to keep your employees honest, and that is why you have controls, so I'm never tempted or put in a position where I could do something to defraud my employer.
I have to be honest with you: When the FBI let me out of prison early to advise the agency on preventing fraud, I wasn't a changed person. I wasn't rehabilitated. But when I started working with the FBI, one of the most ethical groups of men and women in the world, I couldn't help but have some of that character rub off on me.
