Apparently less than 2% state prisoners caught with a military style semi automatic or automatic gun
why talk about state prisoners and not gun crimes? Well the answer is spin and deception. you see less than 20% of state prisoners committed a gun crime.... Thus with this littel trick one has reduced the figures five fold.
a more honest statement would be
10% of criminals in state jail for gun crime used a....
less than 1% of armed criminals sourced their gun from a gun show

Here's the source table and boonmee's handlers are right less than 1% of firearms are sourced from gun shows. About 68% are obtained from friends, family, drug dealers and fences and one has to wonder how many of these guns were untracable guns baught at a show? a legitimate question.
But what really stands with all of this talk of taking personal responsibility for what ones does with guns clearly does not work given that 40% of guns come from family and friends. The bit the gun lobby seem to miss out is that the concept of responsibility is meaningless without accountability... something that separates children from adults.
You buy a gun, you are accountable to varying degrees for what's done with it... really until you pass it onto another gun dealer at which point it becomes their issue. rather like a car. except little of this accountability exists, the gun lobby, the nra, those who talk most about personally responsibility are those who are fighing most to keep gun owners from having to face accountability for what they lets their gun be used for.
