Janet Napolitano has signed a bill into law prohibiting any government body from preventing state-certified police officers from carrying a gun. Currently policy doesn't allow certified officers who patrol Maricopa County community college campuses to carry firearms. "We felt extremely vulnerable because we have gun instances all the time," said Lynn Bray, acting director of security at Mesa Community College and a 20-year Mesa police officer. "I've taken concealed weapons off people all the time." "It's quite ridiculous. Why hire police officers if you're not going to give them the tools to do their job?" Bray said. Arming police officers is just one change coming to the community colleges. Bray said the college has spent the past six months implementing aphone system that can convert telephones into loud-speakers with thepush of a button. The system could be activated to warn the campus of emergencies. Within the next year, Bray said officials will also create a loudspeaker system for common areas and install electronic bulletin boards forthe hearing impaired.
