Kerry Kennedy, the daughter of Robert F. Kennedy, was acquitted Friday of drugged driving on an interstate highway in 2012. 

Kennedy's lawyers said the case would have never been brought if she were "Mary Housewife" and not a member of the esteemed Kennedy political dynasty. 

A six-person jury took around one hour to find Kennedy not guilty of driving while impaired after four days of testimony, the Associated Press reports. 

She was arrested in 2012 after swerving into a tractor-trailer on a highway in her Lexus. 

Kennedy, 54, who is also the ex-wife of New York Gov. Andrew Cuomo, testified that she took a sleeping pill instead of her thyroid medication by mistake on the morning of the car accident. 

If she was convicted, she would have been sentenced to one year behind bars, although that sentence probably would not have been carried out because she was a first-time offender. 

Her lawyers made sure to talk about her infamous family during the trial. Yet, after the trial, Kennedy's lawyers accused prosecutors of giving her special treatment because of her family name by refusing to drop the case. 

The district attorney's office denied the allegation, and Kennedy, who is a human rights activist, said she was not upset about going to trial. 

Kennedy's 85-year-old mother, Ethel, attended the whole trial, and almost a dozen other Kennedy family members also came by to show their support, including her brothers, sisters, sister-in-law and daughters. 

Tobe Berkovitz, a political media consultant and professor of advertising at Boston University, said, "The Kennedys saw this as a DA overreaching, making a big case out of a silly mistake. So they absolutely played every Camelot trump card they had in the deck. They had the family. They had questions about her losing her father as a young girl."

He added, "When the legacy is being challenged, they all step up and fight."

The trail received so much media attention that it was moved from a small courtroom to the county courthouse in White Plains, N.Y. 

During the testimony, Kennedy said she did not have any memory of the ride on the highway. 

"If I realized I was impaired, I would have pulled over," she told the jury.

Prosecutors said she did not intentionally take the drug Zolpidem, but that she must have known she was impaired, and should have pulled the car over. 

The charge was a misdemeanor, which rarely goest to trial, but Kennedy would not settle the case and judges refused to dismiss it. 

Kennedy's lawyer, Gerald Lefcourt, told jurors that Kennedy was "not seeking advantage because of her family."

The district attorney's office in Westchester County disputed the suggestion that she received special treatment. 

"We prosecute 2,500 impaired driving cases annually in Westchester County," the office said in a statement. "This case was treated no differently from any of the others."

After the verdict, when Kennedy was asked if she was angry that the case went to trial, she said, "Anger is the last feeling I've got right now."

She also said that people need to look at the U.S. justice system and "make sure it really is just and everyone in our country has true access to justice."
