Retired LA police robbery-homicide Detective Greg Kading said the deal may have prevented Davis's words from becoming self-incriminating, but officials could still use the information as an investigative tool. Later, in around 500 BC, writings of the Greek poet Sophocles attributed the invention of the dice to a mythical hero and the siege of Troy. Whether or not you buy the fantastical theory, Sophocles' writing shows that the Ancient Greeks used die. Davis, known as 'Keffe D', is thought to have made a deal with federal investigators in California in 2009 that allowed him to speak openly on a number of topics - including what he knew about the hip-hop star's death in Las Vegas in 1996.

Today, double-zero roulette is referred to as American roulette and is the most popular variation. Half a century later, the European roulette wheel, with only one red number instead of two plus a green zero, was developed. Double-zero roulette, in its modern form, was invented in Paris during the late 1800s. The first gambling establishments comparable to modern-day casinos emerged in 17th-Century Italy. The most famous of these, the Ridotto, was established in Venice in 1638 as a controlled environment for gambling during carnival season. Of course, this ban was nearly impossible to enforce. Popular locales for such establishments were steamboats on the Mississippi River, the perfect setting for skirting the law. Instead, the practice simply shifted to illegal gambling houses. At this time, the government caved to puritan pressure and imposed a national gambling ban. The exact details of any agreement between Davis, 60, and federal investigators in 2009 are unknown, but officials may still be able to use his statements as an investigative tool as they continue to probe the case.
