SAN FRANCISCO (AP) — Two mass killings just 10 days apart sent spasms of shock through the San Francisco Bay area and also took a toll on the police officers who had to sort out the carnage. In San Francisco, an unusually high number of officers, about 30, sought counseling after witnessing the gory scene following the massacre of five people inside a home. "Cops see things on a day-to-day basis that the outside world and the average person doesn't," said police union president Gary Delagnes.
