And there's all of this, which I researched and compiled myself.
First, violent crime, including homicides, and including homicides involving guns, is on a downward trend in the U.S. See these tables for the homicide trends, see other tables in the same source for other crime trends:
FBI 2001-2005: Expanded Homicide Data Table 7 - Crime in the United States 2005
FBI 2006-2010: FBI — Expanded Homicide Data Table 8
FBI 2011: FBI — Expanded Offense Data
Facts. Provided by our own government.
Furthermore, raw data aside, our homicide rate in 2011 was 4.8 per 100,000 population, the lowest it’s been since 1963, and less than half of 1980’s high mark of 10.2
Secondly, in the meantime, concealed carry laws have expanded to the point where now, only Washington D.C flat-out prohibits it. Even hold-out Illinois legalized it recently but it won’t be implemented until their legislature works out the details.
Bottom line: Violent crime is down, even though concealed carry is up…way up. Easing Restrictions on Gun Permits - Graphic - NYTimes.com
Thirdly, there are hundreds of thousands, and by some estimates well over a million, defensive uses of guns annually in the U.S. Saint Louis University Public Law Review
Fourth, let’s look at the efficacy of gun ownership bans as illustrated by two cities where legal gun ownership is a virtual impossibility, and where, if the national trend were to be observed, violent crime would be going down, but it isn’t: Chicago and Washington D.C. First, Chicago: Crime in Chicago - Wikipedia, the free encyclopedia
Despite being one of the hardest cities in the country in which to legally keep or use a gun, its homicide rate is going UP. If gun control worked like its proponents said it did, the trend would be going down, and would be approaching zero. It’s not. In fact, 2012 is set to show the highest number of homicides in 5 years, and I say again, this, despite the fact that civilian gun ownership is tightly restricted and concealed carry is banned.
Next: Washington DC. http://en.wikipedia.org/wiki/Crime_in_Washington,_D.C
. Again, gun ownership is damn near impossible, but the violent crime rate fluctuates, and while it may be sharply lower than it was 15 years ago, it is markedly the same for the past several years. How is this possible, in a place where guns are supposed to be nonexistent?
The only conclusions I can draw are that 1) disarming law-abiding civilians does not get the guns out of criminals’ hands, and does not make the population safer, and 2) The proliferation of guns and of concealed carry have not contributed to an increase in violent crime.
Lastly, if you have the time and further inclination, these are two of the better pieces I’ve seen on the gun control and on the futility of an AWB:

Researching these things points out the bull#### coming at us from BOTH sides of the debate, and I’ve tried hard to stay away from hyperbolic twists of stats such as those pointing to higher crime rates in U.K. and Australia.
