Like one police officer in Arkansas, caught on tape stealing money during a traffic stop of a suspected dealer.
Or Louisiana judge Alan Green, convicted of taking bribes. He was caught on camera in his office, accepting cash from a man saying he was "delivering on my promise" and recommending that he "put that away somewhere."
Green's response, as heard on the tape: "I appreciate it."
Government prosecutors pushed for a tough sentence for the former judge, writing in their sentencing memorandum that in exchange for the bribe money Green received, he "harmed innocent victims by releasing dangerous criminals" at the request of a corrupt bail bonds company.
A judge sentenced Green to four years and three months in prison.
In another shocking example, investigators caught the superintendent of the Prince George's County, Md. public school system sitting in a hotel room, relaxing with a bottle of champagne while accepting a cash bribe.
Andre Hornsby is seen enjoying the champagne and the cash from a fake company he set up to get kickbacks on county school projects he had a role in approving.
As a female informant hands over a thousand dollars, a down payment on the $100,000 anticipated, Hornsby picks it up from the table, puts it into his pocket, and says, "That's just Christmas money."
Hornsby was sentenced to six years in prison followed by three years of supervised release in November 2008.
"Greed, entitlement, a sense of power, ego -- those are things that drives the public corruption," Kaiser told ABC News. "I am always amazed at how brazen -- and the entitlement people feel."
