You're a smart guy so you know statics are dependent of unbiased data collection and accurate numbers. Since the number of guns in the USA is "estimated" to be 270 to 310 million guns, which is a variance of  40 million guns, I say no accurate statics are possible since no accurate base exists. Besides most gun statics are NRA generated and are spun to support a desired result. The truth is we are afraid to acknowledge or confront the Frankenstein we have created because it's so undeniably big.
