Out of the rampage near UCSB comes this:

Just days after a 22-year-old killed six college students and himself near the campus of the University of California, Santa Barbara, state lawmakers are championing legislation that would permit law enforcement officials and private individuals to seek a restraining order from a judge that would keep people with a potential propensity for violence from buying or owning a gun. The process would be similar to the one currently used for restraining orders in cases of domestic violence.

According to this New York Times story, laws like what's now being proposed in California are already on the books in three states—including deep-red Texas.
