In 1998, Barnicle resigned from
The Boston Globe due to controversy over two columns, written three years apart. The first column, published on August 2, 1998, consisted of more than 80 humorous observations and included "a series of one-liners that had been lifted from...
George Carlin's best-selling 1997 book,
Brain Droppings." Barnicle first received a one-month suspension; he denied that he had ever read the book and claimed that the jokes were told to him by a bartender. After the emergence of this second controversy, Barnicle resigned from the paper on August 19, 1998. The magazine
Boston began a 'Barnicle Watch' in the early 1990s to try to track down other dubious Barnicle sources to which
Globe Editor John Driscoll responded: "He's visible, he's on the street, he's talking to real people. He doesn't need to make things up." Barnicle's resignation spurred reanalysis of his reporting on the 1989
murder of Carol Stuart and "most of the reporting proved solid," according to
The New York Times. He and Kevin Cullen had reported that
Prudential Financial had issued a check for $480,000 to Stuart’s husband as the
life insurance payout for his wife's policy, offering a potential motive for her husband's decision to kill her.
The Boston Globe, according to a column by Adrian Walker on December 11, 2023, "stood by its reporting."
The New York Times later confirmed that Carol Stuart did not have an insurance policy with Prudential but that there were other policies, including one that yielded a payout of $82,000 from the firm where she worked as a lawyer.
The Boston Globe came under criticism in the 2023 documentary about the case,
Murder in Boston, for the paper's reporting on Willie Bennett, the ultimately innocent man who was accused of the crime.
The Boston Globe published Bennett's grade school report cards, his IQ, and the fact that he did not finish the seventh grade in a column by Barnicle. After the release of the documentary, Boston Mayor
Michelle Wu issued a formal apology to the Bennett family on behalf of the city. ==Post-Globe career==
