Comparing/Contrasting areas of restriction of rights VS right to carry areas:

The states on this map in shades of blue either allow legal carry on campus (dark) or leave the decision up to individual campus leadership (light blue). States in red do not allow the 2nd Amendment rights to extend to those on campus. States with hashed lines are currently considering campus carry legislation.

States in red do not abide by the Second Amendment's admonishment regarding "shall not infringe"

Results of these decisions:

The University of Texas in Austin has allowed for concealed carry on college campuses for the last two years. Since then, they have seen a decrease in violent crimes on their campus. The University has not had the explosion of crime that many predicted after the they allowed guns to be carried by students on campus. Contrast this with Texas Tech University,  a campus within the same state that has not allowed  on campus carrying, and that has actually seen a slight increase in reported violent crimes according to the Texas Tribune article. (Platoff)

Likewise, college campuses in Kansas, which recently has allowed campus carry, has also seen a marked decrease in campus crimes in the span of a year.

2016 2017
General Crime rate 770 671
Assaults 30 14

Furthermore a 66% decrease in car thefts was reported however, exact numbers were not given. (Patrick)
The Supreme Court supported Texas’ Campus Carry legislation just this year (2018). (Pollock)

In Colorado, where the legalized ability to carry on campus has been allowed since 2003, Colorado State University quickly complied with the law, and allowed carry on campus. “In 12 years of licensed carry at CSU (Colorado State University), there have never been any problems caused by licensed carriers.”

According to research done by the U.S. Census Bureau data by Florida State University criminologist Gary Kleck, it was found that somewhere between 830,000 and 2.45 Million defensive gun uses per year in the United States. (Cramer and Burnett)

Reporting from the Cato Institute further shows “a dramatic expansion of the number of people licensed to carry concealed weapons” and also these weapons are used for more than defense against human attackers, but often are deployed against attacking wild and domestic animals. Also, allowing law abiding citizens to carry a weapon does not lead to criminals taking away these weapons and using them. The data set they used shows only 11 times out of 4,699 incidents where the criminal took a gun away from the citizen, and tellingly, 20 times where a citizen disarmed the criminal. (Cramer and Burnett). This same report gives many chilling descriptions of cases where citizens deployed firearms in cases of protection, including over 150 cases of women deploying a gun defensively. For our purposes, however, some interesting findings were in this report:

reports now indicate the rate of crimes on college campuses is rising at a time when overall crime rates are in decline.
...
One wonders what the rate of crime would look like if defensive gun use were introduced as an option on college campuses. What if the Virginia Tech massacre could have been cut short like the New Life church shooting in Colorado?
...
In fact, after Colorado’s 2003 concealed carry law was enacted, Colorado State University decided to allow concealed carry, while the University of Colorado prohibited firearms. The former observed a rapid decline in reported crimes, while the latter, under the gun ban they claimed was for safety, observed a rapid increase in crime. Crime at the University of Colorado has risen 35 percent since 2004, while crime at Colorado State University has dropped 60 percent in the same time frame.

This last fact paints starkly the differences in a campus that allows students to protect themselves from criminal activity, and a campus that actively prevents students from being able to protect themselves.
