And you know for a fact that the reason violent crime went down is because gun ownership is up? This is horseshit. I don't believe it for a second.
I'll bet you that violent crime will increase significantly in the next 5 years. It won't have anything to do with how many people own guns. It will have a lot to do with how many people who are doing very poorly financially have access to guns, immediately or potentially.
A large number of violent crimes are crimes of desperation, and there is going to be a lot more desperate people in the not so distant future.
The crime statistics of the 70s vs 80s vs 90s are mostly driven by crack cocaine's rise and fall.
There is probably a similar correlation with meth and the last two decades.
