Quote:Currently in California, authorities can seize legally purchased guns only from people convicted of a felony or a violent misdemeanor, those subject to a domestic violence restraining order, or those who are determined to be mentally unstable.
So you get into the whole issue of who makes those decisions. Before shooters start shooting you would have to get a judge to classify them as mentally unstable.
