HOUSTON — Jaime Escalona was fleeced so thoroughly by the financier R. Allen Stanford that he could no longer pay for his grandson’s autism treatments, he said in a steady voice in court on Thursday, before turning to the defendant and declaring, “You are a dirty, rotten scoundrel.”

Mr. Stanford took the insult in stride, and stared right back.

Then Angela Shaw Kogutt, who said three generations of her family had lost over $4 million because of Mr. Stanford’s “financial terrorism,” asked all the scores of victims in the federal court gallery to stand before Mr. Stanford to show him their faces of misery. Judge David Hittner of the Federal District Court told Mr. Stanford he was under no obligation to look, but he swiveled his chair toward the victims anyway without a flinch or sign of caring.

For Mr. Stanford, his day in court on Thursday — the day he was sentenced to 110 years in prison without parole for masterminding a $7 billion Ponzi scheme — was anything but a time for contrition. Instead, after refusing to testify in his own trial, Mr. Stanford broke his silence to say that unlike Bernard L. Madoff, the most prominent of Ponzi scheme swindlers, “I am not a thief.”

Rather, he said, he was the victim of government “Gestapo tactics” that provoked a run on his Caribbean bank and then sold off his assets at bargain-basement prices. Anyone who lost their money, he said, did so because of the government’s “unnecessary” actions.
