Five years after the Virginia Tech massacre prompted a student in Texas to start a Facebook page in favor of the right to carry concealed weapons on college campuses, the resulting group, Students for Concealed Carry, has advanced its cause. In more than a dozen states, legislation has been introduced to allow the carrying of concealed firearms on public-college campuses or to soften gun bans there. But the student group's attempts to spread the message have met resistance. Many administrators are opposed to allowing guns on their campuses and interpreting the language of concealed-carry laws in restrictive ways. Students for Concealed Carry has had a two-part mission since its inception. First, members seek to send a message about the importance of guns in maintaining a safe campus. Second, they work to change state policies to legalize the concealed carrying of weapons by licensed permit-holders on college campuses. Leaders of the organization, who argue that there are many misconceptions about carrying a concealed handgun, hope that they can dispel public anxiety about the issue and raise awareness of the benefits of carrying a weapon for self-defense. Five years after its founding, Students for Concealed Carry has built a national support network for student groups that are in favor of extending gun rights to college campuses. But it has run into some challenges, too. Setting up campus chapters has proved difficult at some colleges, where faculty are reluctant to sign on as advisers to pro-gun student groups, even if they support the idea.
