Americans are reporting a slightly higher percentage of serious violent crime to law enforcement, but there is a long way to go.  A U.S. Bureau of Justice Statistics survey issued today concluded that in 2010, 42 percent of incidents in a crime category that includes rape/sexual assaults, robberies and aggravated assaults went unreported.  As bad as that sounds, it has been worse.  In both 2009 and 1994, half of serious violent crimes weren't reported. When simple assaults are added to the mix, 52 percent of overall violent crimes are not reported--nearly 3.4 million incidents annually.
