Nearly all campus police officers at public universities now carry guns, pepper spray and other weapons, according to a new Bureau of Justice Statistics Department report.
Overall, about two-thirds of public and private campuses used armed officers during the 2011-12 school year, according to the Bureau of Justice Statistics survey of 900 four-year colleges with at least 2,500 students. Officers at public universities were more than twice as likely as those at private schools to carry guns.
