One statistic that is truly shocking is the Alaskan rape rate. 5 times higher than some rates in the east.
Why? Surely guns stop this sort of thing, or maybe they can just make it worse.
Actually, they might.
Rape is an "ambush" crime. Most rapists come up on women when they least expect it like when they are opening a car door in a parking lot or garage. And women will keep their handguns in their purse. For the most part it's impossible for them to get to it and the Rapist may make use of it.
Yeah, they "might", but it appears that more guns equal more rape, whether it's guns that cause a higher rate of rape is a different matter.
The average rape rate in the US was 26.9 in 2012
United States Crime Rates 1960 - 2012
Alaska is 79.7
Looking at this map of how laws are going in different states after the Newton gun killing.
Those who have passed pro-gun bills are
South Dakota 70.2
Arkansas 42.3
Maine 28.0
Mississippi 27.5
Two of which are massively over average, and two of which are a bit higher.
New York the only one which has past anti gun laws is at 14.6
Now, you could go through all the stats, and you'd find states that have less guns laws and more guns in the hands of people but lower than average rape rates, and others which have are higher.
FBI ? Table 4
However the North East is 19.7
The mid west is 31.7
The south 27.1
The West 27.5
So the lowest area for rape is the North East which is the most liberal of areas, some of the stricter gun laws.
Now, are there other things that have an impact?
Compare States Education Spending for 2014 - Charts
I looked at how much local and state spending goes on education per capita. Alaska has the highest spending, which is worrying.
But, if guns can stop rapes, the question is whether they do so more than they empower men to commit rape with guns when otherwise they wouldn't. Hard to say really because you aren't going to find such stats.
