UPPER DARBY, Pa. – A man who had posted an online video threatening to kill police and FBI agents tried to use his car to run down officers seeking to arrest him on Tuesday so, fearing for their lives, they shot and killed him, authorities said.

Police did not immediately identify the man, who was killed in Upper Darby, in suburban Philadelphia, as officers ordered him out of the car and he appeared ready to accelerate at them as they manned a blockade.

Police Superintendent Michael Chitwood said the officers feared the man would kill them and they “did what they had to do.” He said five officers fired at the man and no officers were injured.

Police had secured an arrest warrant for the man after he threatened to kill police and FBI agents in the online video, Chitwood said. Police said they began following the man after he left a home in nearby Clifton Heights. They said when officers stopped him at an intersection and ordered him out of the car, he reversed and slammed into a police vehicle and then prepared to run over other officers.

Officers opened fire, killing the man, Chitwood said. The man did not fire at police, and Chitwood said he did not know if the man had a weapon.

N.Y. mayor meets with police union

NEW YORK – Mayor Bill de Blasio met privately for more than two hours Tuesday with the leaders of the New York Police Department’s unions, aiming to mend a rift with rank-and-file officers that has threatened to overwhelm his young mayoralty.

While administration officials characterized the meeting as the beginning of a process to heal wounds opened by protests about police conduct and the fatal shooting of two officers, union leaders struck a more cautious note, saying that “only time will tell” if relations would improve.

“Our main concern is the safety of our police officers of every rank on the streets in the city,” said Patrick Lynch, head of the Patrolmen’s Benevolent Association, which represents rank-and-file officers, after the meeting.

“There were a number of discussions especially about the safety issues that our members face,” Lynch continued, reading a joint statement from all five unions. “There was no resolve. And our thought here today is that actions speak louder than words and time will tell.”

Lynch has been one of de Blasio’s fiercest critics, saying the mayor had “blood on his hands” after the brazen daylight ambush of two officers in their patrol car earlier this month.

George H.W. Bush home from hospital

HOUSTON – Former President George H.W. Bush was released from a Houston hospital Tuesday after a stay of about a week for treatment of shortness of breath.

The 90-year-old Bush left Houston’s Methodist Hospital, was resting at home and is “grateful to the doctors and nurses for their superb care,” family spokesman Jim McGrath said in a brief statement.

Bush, the oldest living former U.S. president, was taken by ambulance to the hospital a week ago for what was described then as a precaution after experiencing shortness of breath. His hospital stay included Christmas.

The former president spent Christmas 2012 in intensive care at the same hospital while being treated for a bronchitis-related cough and other issues.

California snowpack still below average

ECHO SUMMIT, Calif. – The winter’s first survey of the Sierra Nevada snowpack on Tuesday found more snow than last year at this time, but officials said much more is needed to end the California drought.

The Department of Water Resources conducted the survey at an elevation of about 6,800 feet about 90 miles east of Sacramento.

Frank Gehrke, chief of the California Cooperative Snow Surveys Program, said 21.3 inches of snow was on the ground after recent heavy storms.

It was more snow than this time last year, but the water content was still far below average for the date.

“California needs much more rain and snow than we’ve experienced over the past two years to end the drought in 2015,” said department Director Mark Cowin. “The department encourages Californians to continue their water conservation practices.”
