From the New York Times obituary of Marion Barry, the former mayor of Washington, D.C.:
Despite his clashes with the law, he won a City Council seat in 2004. The next year he pleaded guilty to two misdemeanor charges for failing to file income tax returns for the year 2000. He was placed on probation for three years. Yet he continued to defy the I.R.S., neglecting for the next several years to file returns. He finally settled with the tax agency in 2009, saying that his failure to file had been the result of his health.
