Doesn't matter. Have you been on a college campus lately? No way in a million years should guns be allowed carried on campus.
Only a person who lacks logic would think that the way to lower gun violence is to arm MORE people with guns. Of course people have shown you stat after stat and you ignore it and continue to post logical fallacies to support your position.
Let me ask you a simple question. Who is at the highest risk to die from gun violence:
A woman in a gun free home or a woman in a home with guns?
If your hypothesis that more guns equals more gun related homicides...let's look more into it. According to the FBI here are the top 10 states in gun ownership (per capita, not raw numbers):
Alaska
Arkansas
Idaho
West Virginia
Wyomig
Montana
New Mexico
Alabama
North Dakota
Hawaii
Here are the top 10 states in homicides where a gun is used (per capita):
Louisiana
Missouri
Maryland
South Carolina
Michigan
Delaware
Mississippi
Georgia
Arizona
Pennsylvania
What you'll notice that there's no correlation between states with gun ownership and homicides where guns are used in the United States.
You are roughly 7 times more likely to be killed in the US than in Canada by a gun, yet Americans are 4 times are likely to own a gun. If the more guns = more homicides we should expect the correlation to be more similar.
We would also expect a large correlation between countries that have a large amount of gun ownership to homicides as well. Canada is 7th in the world for gun ownership. They are 29th in homicides.
The problem with mass shooting in the US (and there's no doubt that it is a problem), is that people don't want to look at the real problem because it makes us uncomfortable: it's our culture, our mentality, and mental health system. Gun killings are the symptom, not the underlying problem.
