how many people were killed by violent crime in the united states in 2006 ?

Answer 1

You can find many crime stats by checking the fbi.gov website or following links to other government websites. The FBI tracks violent and other crime by the UCR.
The UCR is the Uniform Crime Report which we have to supply to the FBI for their statistical data tracking.
Another source for stats is department of justice website. It may be DOJ.gov they have a vast amount of information.
