Can the zebra change it's stripes? If you're a black hat hacker, will you always be one? What if you're one of those "I messed up, I was busted, did time, but now I'm a good guy, trust me" types ... do you deserve a 2nd (or 3rd...) chance? Does it make sense that the best people to teach you how to safeguard your valuables are the convicted crooks?
Is it really that easy? ...obviously not.
