SAN JOSE — Heading into the holiday weekend, the San Jose Police Officers’ Association released a provocative online video calling attention to a national spike in officer killings in the past year and contending a lack of outrage about the trend.

It also alarmed local civil rights leaders who called the web video divisive and insensitive to minority communities fearful about the election of Donald Trump as president.

Titled “When did shooting at cops become OK?”, the minute-long video posted to YouTube and released early Wednesday cites that 56 police officers in the United States have been shot to death so far in 2016, marking a 70 percent rise in such killings during the same period in 2015. Since the video posted, a 57th officer died.

At a news conference Wednesday at its San Jose headquarters, a mock Thanksgiving table was set up, adorned with portraits of American law-enforcement officers recently killed on the job.

“We owe it to them to have their memories discussed at the Thanksgiving table,” union president Sgt. Paul Kelly said. “Enough is enough. I’m not going to continue to be quiet when officers are getting ambushed across the nation.”

The latest killing was confirmed Wednesday in Detroit after a Wayne State University police officer was shot in the head while stopping someone on a bicycle Tuesday night. On Sunday, a San Antonio police officer was shot during an apparent ambush. In the greater Bay Area, Stanislaus County Sheriff’s Deputy Dennis Wallace was fatally shot Nov. 13 by an auto-theft suspect in Hughson, about 10 miles southeast of Modesto.

Backed by a somber piano track, the union’s web video asks, “Where is the outrage” and “Where are the protests?” interspersed with news footage about a Nov. 13 encounter where an alleged gang member shot at two gang-enforcement officers at close range in East San Jose. The officers were not hit, and the man suspected in the shooting was arrested four days later.

That was the second in time this year that someone fired at SJPD officers. On a March 12, during a car stop, a man fired at three officers with a rifle. The last department member shot and killed in the line of duty was Officer Michael Johnson in March 2015.

The video ends by saying “The San Jose Police Officers’ Association believes All Lives Matter” and “Blue Lives Matter.”

Those slogans were created as a protest to “Black Lives Matter” demonstrations over the killings of unarmed black men by police, dating back to the 2014 death of Michael Brown in Ferguson, Missouri. Police advocates accused people in the movement of unfairly vilifying police.

Silicon Valley De-Bug Director Raj Jayadev, one of SJPD’s most prominent critics, said the video only serves to inflame the very tensions the union is trying to quell.

“Anytime an armed force with a license to use lethal force says it is ‘drawing a line in the sand’ — it should be understood as a very serious threat to the public,” Jayadev said. “If their goal was to ratchet up the tension between the police and the community, and further build distrust and suspicion — they nailed it.”

Kelly said a national animus against police contributes to the recent rise of fatal officer shootings, which he said was becoming “the new normal” and has been fueled in part by what he called “false narratives” and misinformation about police shootings. The union is also advocating for federal legislation that would designate the targeting and killing of a police officer as a hate crime.

Kelly noted that San Jose has so far avoided a major controversy, but he voiced wariness about the effect broader sentiments could have locally.

“We get along with our community,” Kelly said. “But all it takes is one incident.”

Walter Wilson, a board member with the African American Community Service Agency, took issue with the union’s characterization of violence against police, citing statistics showing that while the country has seen a spike in the past few years, officer deaths have consistently trended downward since the 1970s.

“This is political grandstanding, and it’s not helpful or useful,” Wilson said. “Where’s their press conference when a black man is killed on video with his hands up? All lives matter, sure they do. But do they matter equally? The answer is no.”

Kelly, the union president, warned people not to lose sight of the lives at stake amid all the charged rhetoric being exchanged.

“I don’t understand why we even need to get into the words, the acronyms, or the hashtags,” Kelly said. “We’re talking about human life.”

Chandra Lopez-Brooks, a community activist, said the video bypassed a dialogue with concerned residents she says would have been more constructive.

“We need these officers to protect and serve, not to call out organizations for the disenfranchised and underserved,” Lopez-Brooks said. “We can just as easily say, why aren’t you marching with us?”
