The following chart is from Common Folk regarding Brady Campaign grading of state gun laws versus crime rates. The claim is, "It would seem that while the Brady Bunch consider a state safe if it has severe gun restrictions, crime is actually more rampant in those same states with severe gun restrictions making them, in reality, less safe."
From this data one could conclude there is an inverse relationship between the Brady score and safety.
Be careful! This data is a subset of the entire population of states. I did a similar analysis for the 2004 Brady Report Card using all state data and the correlation was near zero. In the comments to the Common Folk link other people arrive at similar conclusions to mine.
Of course you won't find the anti-gun people doing peer reviews such as this and pointing out the errors. Nope. They cherry pick their data and report just what they want people to hear.
