"If she wasn't Lindsay Lohan, she wouldn't do more than about six hours," said Geragos, calling the sentence "almost draconian."
Referring to the explicit message on her fingers, Geragos added that there's no restriction by the U.S. Supreme Court on wearing profanities.
After the hearing, Lisa Bloom, the attorney for Lohan's estranged father, Michael, said that if Lohan had followed their advice and gone to rehab, she might not be facing jail time now. Michael Lohan has long maintained that his daughter is addicted to prescription drugs.
"If she had gone to rehab anytime over the last several months, when we were begging her to go to rehab, she could have avoided all of this," Bloom said Tuesday. "Where she belongs is rehab. We don't believe incarceration is the place for addicts."
Before the verdict came down, Lohan said she was doing her best to comply with her probation.
"I just wanted to take a minute to say that, as far as I knew, I was being in compliance with my programs," she started. "When I asked to leave town [the alcohol ed program] would give me permission to leave town."
After tears started rolling down her cheeks, Lohan held her head in her hands as she tried to compose herself. She went on talking, and at times, sounded incomprehensible.
"I know that I was ordered to go once a week. ... I was working, mostly, I was working with children, it wasn't vacation, it wasn't some sort of a joke," she said, sniffling. "I wanted to make sure that I would come back here making you happy and the court system."
Lohan's Tuesday hearing lasted for hours. Shortly after it began, Revel demanded to see documents detailing Lohan's performance in the Right On alcohol education program. Revel called a recess so that prosecutor Danette Meyers could review the documents.
Meyers went to great lengths to show the degree to which Lohan violated her probation by failing to attend weekly alcohol education classes according to the schedule set by Revel.
"She knew [the prosecutor] would be asking for jail time and yet still after all that, she didn't comply with the court order and the court does find her in violation of her probation," Revel said.
Also at issue: Lohan's SCRAM -- secure continuous remote alcohol monitoring -- bracelet, and whether the fact that it went off on June 7 should be considered in determining whether or not she violated her probation. Ultimately, Revel decided the hearing would focus only on Lohan's alcohol ed class attendence, despite the fact that SCRAM experts flew in to potentially weigh in on the device.
Two representatives from the Right On alcohol education program testified at the hearing. Cheryl Marshall, co-owner of Right On, said that Lohan failed to attend the required minimum of one class per week nine times, but Right On never notified the judge that there was a problem. She added that Lohan came up with a variety of excuses for missing class.
That didn't sit well with prosecutor Meyers.
"[Lohan] clearly violated your orders," she told the judge. "She was to abide by all rules and regulations of the court."
