5 years for blowing off your drivers head with a shotgun:
Murder/manslaughter charges
In the spring of 2002, Williams was tried for the shooting death of 55-year-old limousine driver Costas "Gus" Christofi at Williams's estate in Alexandria Township, New Jersey on February 14, 2002.[4] Christofi had been hired to drive Williams's NBA charity team from a Bethlehem, Pennsylvania event to his mansion, about 30 miles (48 km) northwest of Trenton, New Jersey. Members of Williams's NBA charity basketball team were present at the scene. The New York Post reported that Williams was playing with a shotgun while giving a tour of his 30,000-square-foot (2,800 m2) home when the weapon fired, killing Christofi.
That April, Williams was acquitted of the more serious charges against him, but the court's jury deadlocked on a charge of reckless manslaughter. He was convicted on four counts of trying to cover up the shooting. In January 2003, the family of Costas "Gus" Christofi settled with Williams in a wrongful death civil lawsuit for $2.75 million.
On April 21, 2006, a Hunterdon County appeals court ruled that Williams could be retried on a reckless manslaughter charge stemming from the shooting death of Christofi.[5][6] The court repeatedly delayed the retrial for a series of reasons, such as the State's 2008 appeal of a ruling relating to prosecutorial misconduct at the first trial.[7]
On January 11, 2010, Williams pled guilty to aggravated assault.[8] On February 23, 2010, he was finally sentenced to 5 years in prison with possible parole after 18 months.[9]
Lesson Learned: When recklessly and unintentionally killing people use a firearm instead of a car.
