Con artists make money through deception. They lie, cheat and fool people into thinking they've happened onto a great deal or some easy money, when ­they're the ones who'll be making money. If that doesn't work, they'll take advantage of our weaknesses -- loneliness, insecurity, poor health or simple ignorance.
