The state Supreme Court ruled Monday that the University of Colorado cannot ban concealed-weapon permit holders from bringing their guns to campus. And while gun-rights activists are celebrating the ruling, CU says it discounts the regents' authority to govern safety on its campuses. Colorado's highest court sided with Students for Concealed Carry on Campus, a gun-rights group that filed a lawsuit against CU in 2008, arguing that a university policy banning concealed weapons from its campuses violates state gun laws.
