The study is of defensive gun uses. It has some really interesting data on college carry.
Apparently Colorado and Utah have between them ~25 college campuses where students with concealed carry licenses are allowed to carry on campus if the college administration doesn't prohibit it. Colorado enacted a concealed carry law in 2003 that allows licensed students to carry concealed weapons on campus. In the CATO study I found the following paragraph on page 17 related to how that's working out:
"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."And there you have it folks, nearly perfect data illustrating the reason why "shall issue" concealed carry should be allowed in all 50 states and DC with full reciprocity, and for licensed students at all universities, especially VA Tech.
I think all that should be required to get a CCW license is the ability to pass the same background check as is required to buy a handgun. Training is both expensive and of little demonstrated value. All that's required could be put on a gun purchase sign off list added to the purchase form already inuse certifying the dealer showed the buyer of the handgun how to load, unload, and clear it, the safety if it has one, had them read "the four rules" and by signing the firm certifying that the buyer understood them. Nobody who needs a gun has to wait for one, everybody walks out of the store knowing the basics about the gun they just bought.
