Security guards will no longer be able to obtain temporary registration cards before a background check is completed. The bill is among those Governor Davis is signing over two days to increase Californians´ security after last year’s terrorist attacks. A second bill responds to two weapons scares at Los Angeles International Airport. He’s signing three other bills Monday while attending a “homeland defense summit” in Ontario, including measures allowing increased state use of wiretaps and boosting penalties for using weapons of mass destruction. They’re among about two-dozen bills that made it to Davis´ desk from the roughly 100 bills proposed after last fall’s terrorist attacks.
