Trials are often mundane proceedings, but Roger Stone's has emerged as a spectacle peppered with vulgar and often obscene language.

Stone's messages with his associates are packed with obscenities, but the once-private correspondence are now on display for everyone—including the jury—to see and hear. And it's shattering the traditional norms of no swearing in the courtroom.

"Prepare to die cock sucker," Stone wrote in one message to associate Randy Credico, which was read out loud for the jury Thursday.

Typically straight-laced prosecutors almost seem to be relishing in the use of vulgarities in the courtroom of U.S. District Judge Amy Berman Jackson of the District of Columbia, as they are using the language to argue Stone pressured Credico into not cooperating with the House Intelligence Committee's Russia probe and potentially even special counsel Robert Mueller's investigation.

Judges have wrestled in the past with how to handle profanity in their courtrooms. They have a lot of freedom on whether they want to quote it from evidence in their opinions or allow it in briefs, never mind whether they want it said out loud during proceedings.

Earlier this year, the U.S. Supreme Court refused to allow the word "fuck" to be said out loud or used in written briefs in a case involving a vulgar trademark for a clothing brand named FUCT. In that case, attorneys got creative in order to avoid uttering the four-letter word before the justices.

Deputy Solicitor General Malcolm Stewart, who defended the constitutionality of the law prohibiting vulgar trademarks, came up with the most creative way of describing the word without saying it during oral arguments: "This mark would be perceived by a substantial segment of the public as the equivalent of the profane past participle form of a well-known word of profanity and perhaps the paradigmatic word of profanity in our language."

In Stone's case, his attorneys said they did not recall an order from the judge about the use of language in the courtroom.

Kadia Koroma, a spokeswoman from the U.S. Attorney's Office for the District of Columbia, said that the "court was aware of the trial exhibits well before they were introduced into evidence."

"Before trial, neither party nor the court raised the issue/question concerning the coarse language included in some of the document evidence," Koroma wrote in an email.

The use of the obscenities in the messages is, at times, so frequent that if they were to be censored out, it could make the messages unintelligible to the jury and others watching the trial. The majority of the vulgar language stems from messages between Stone and Credico.

The task of repeating the messages mostly fell to Michelle Taylor, the former FBI agent for Stone's case. She left the bureau in August to join a private consulting firm, but was called to the stand Wednesday and Thursday to submit the majority of the evidence into the trial.

And so it was from Taylor, a young woman, that the jury heard most of the profane messages between the two older men.

"I know u are a dumb shit but read the Constitution. I have a constitutional right to call you a lightweight pantywaist cocksucker drunk asshole piece of shit and I just did," was one of Stone's messages to Credico that Taylor read out loud.

Bruce Rogow, Stone's Fort Lauderdale, Florida-based attorney, has admitted that the messages can be tough to read. "They're profane, they're rude, they're crude," he said during his opening statement Wednesday.

However, he argued, that's just the way Stone and Credico talk. Rogow painted a picture of a tumultuous relationship between Stone and Credico, who have opposing political beliefs.

Credico, during his appearance on the stand Thursday and Friday, refrained from repeating the vulgar language presented to him, even if it was from his own messages, choosing instead to trail off at the end of one such sentence.

"Do I have to pronounce these four letter words?" he asked, when reading out loud some messages between him and Stone. The prosecutor said Credico could omit them; Credico used the word "blank" instead.

"Waste of your time, tell him to go blank himself," was Credico's reading of one such message from Stone to him, about special counsel Robert Mueller.
