A Later Last-Call for California Bars?

California cities and towns could allow bars and restaurants to serve liquor until 4:00 a.m. under a proposal by State Senator Mark Leno. Currently, the state permits booze service from 6:00 a.m. until 2:00 a.m. The San Francisco Democrat says the extended hours would boost employment and promote tourism. But critics contend that the change could lead to more crime and encourage drinking and driving.
