The problem with the UCRs is that the data is reported by individual law enforcement agencies and is often incomplete. For example, during its reign as murder capital of the U.S., DC would often not report data by the deadline, causing the FBI to estimate numbers based on previous reports.
The CDC mortality data is more accurate but doesn't break out cause of death as specifically as the FBI's since it is filled out by doctors rather than investigators.
I am glad to see all that gun control crap in California is working. They topped the list with 1,790 total deaths. The even had 101 murders that were committed by hands, fists or feet. You sure don't see those politicians using those stats to further their gun control cause.
