Gov. Jerry Brown has signed a bill banning concealed weapons from California schools and universities, a measure that drew renewed attention after a recent massacre at an Oregon community college.

SB707 by Democratic Sen. Lois Wolk of Davis will prohibit people with concealed weapons permits from carrying firearms on school and college campuses.

People who have concealed carry permits would be allowed to carry firearms within 1,000 feet of a public or private K-12 school, but not on the grounds.

Retired law enforcement officers who are authorized by their former agency to carry concealed weapons would be exempt. Police chiefs and school districts could also set their own concealed weapons policies.

Gun owners' groups said they would/would have immediately sued to challenge the bill that Brown approved on Saturday.
