LA fugitive manhunt brings heavier Grammy policing

There was a heavier-than-usual police presence at the Grammy Awards because of a dangerous former Los Angeles police officer believed to have killed three people in a region-wide rampage last week.
 
Police Cmdr. Andy Smith says the always heavily guarded Grammys saw even more officers at Staples Center on Sunday as the hunt for 33-year-old fugitive Christopher Dorner continued.
 
The search was focused in mountains 80 miles away, but police said Dorner could be anywhere, and most of the targets he threatened in an online manifesto have ties to the LAPD -- which typically has a visible presence at the Grammys.
 
Scores of officers were outside Staples, others were stationed on a hotel roof across the street and Grammy participants' credentials were being checked constantly.
 
Dorner's manifesto mentions many celebrities, but makes no threats to entertainers.
