Are more guns being purchased the reason behind a drop in murder 2007-2011? Maybe get the numbers for the population increase and it might produce some interesting stats (266,314,667 as of 2012, Legal citizens): FBI — Expanded Homicide Data Table 8 Preliminary results for 2012 are -1.7% drop (of total population): FBI — Table 1 So murder drops yet again in the year of record breaking gun sales. Something here is telling me the problem is guns in the hands of criminals and not the general population. Here is a nice FBI stat on Justifiable Homicide: FBI — Expanded Homicide Data Table 14 Of course the US media with all thier flashy graphics and bite size statistics have failed to provide the viewers with this data, The FBI even provide the data in Excel spreadsheets so it's easy to import into other software. Agenda driven, hippy lazy journalism.
