In what is perhaps the most boring run in with the law in the history of presidential candidates, Mitt Romney was arrested in 1981 for launching his motorboat in a Massachusetts lake. Moments before the launch, a police officer had told him not to or to face a $50 fine. Romney went for it anyway.
From the Boston Globe via RedState:
The charges against Romney were dropped several days later and officially dismissed in February 1982 at Natick District Court. At Romney’s request, the judge also agreed to seal the records, making them unavailable for public inspection.
Romney said yesterday that the park ranger had overstepped his authority in arresting him and said the reason the case was dropped was that he had threatened to charge the officer and his agency, then called the Department of Environmental Affairs, with false arrest.
“He did not have the right to arrest me because I was not a disorderly person. This was an obvious case of false arrest,” Romney said. “The officer obviously agreed because he agreed to dropping the case.”
