Brown said the suspect, who he would not identify, told a hostage negotiator that he was upset about the Black Lives Matter movement and the recent police shootings of black men elsewhere in the U.S.

Dallas police chief David Brown said all we need to know about the inspiration and motives of the thug who assassinated five Dallas cops. As NBC News reported :

The Dallas shootings are the logical extension of the demonization of police officers by the racial grievance industry spearheaded by the Black Lives Matter movement, a demonization that began almost as soon as President Obama took office. As Fox News reported in 2009:

Many police officers across the country have a message for President Barack Obama Get all the facts before criticizing one of our own. Obama's public criticism that Cambridge officers "acted stupidly" when they arrested black Harvard professor Henry Louis Gates Jr. could make it harder for police to work with people of color, some officers said Thursday. It could even set back the progress in race relations that helped Obama become the nation's first African-American president, they said.: "What we don't need is public safety officials across the country second-guessing themselves," said David Holway, president of the International Brotherhood of Police Officers, which represents 15,000 public safety officials around the country. "The president's alienated public safety officers across the country with his comments."

Ever since that day police have been second-guessing themselves, beset by accusers who find them guilty of racism and excessive force. In their eyes police are guilty of racism until proven innocent. That BlackLivesMatter was credited by the assassin of being a source of his racial hatred and hatred of police is not surprising. After the Ferguson riots, the movement quickly spread, framing the confrontation as not one between criminals, such as the black youth who had just committed a strong-arm robbery of a convenience store, and law enforcement. They painted Officer Darren Wilson, who was later found to be justified in shooting the black youth who tried to kill him with his own gun, as the poster child for police brutality that willfully and indiscriminately targets minority communities.

We saw their bloodlust in New York as “protesters” of police brutality chanted their lust for dead cops. As Heather MacDonald writes in her new book, The War On Cops (Encounter Books, 2016):

In the summer of 2014, as we have seen, a lie overtook significant parts of the country and grew into a kind of mass hysteria. That lie holds that the police pose a mortal threat to black Americans— indeed, that the police are the greatest threat facing black Americans today. Several subsidiary untruths buttress that central myth: that the criminal-justice system is biased against blacks; that there is no such thing as a black underclass; and that crime rates are comparable between blacks and whites, so that disproportionate police action in minority neighborhoods cannot be explained without reference to racism. The poisonous effect of these lies manifested itself in the cold-blooded assassination of two NYPD officers in December that year. The highest reaches of American society promulgated those untruths and participated in the mass hysteria. President Barack Obama, speaking after a grand jury decided not to indict the police officer who fatally shot Michael Brown, declared that blacks were right to believe that the criminal-justice system was often stacked against them. Obama repeated that message as he traveled around the country subsequently. Eric Holder escalated a long-running theme of his tenure as U.S. attorney general: that the police routinely engaged in racial profiling and needed federal intervention to police properly…. Meanwhile, protests and riots against the police were gathering force across the country, all of them steeped in anti-cop vitriol and the ubiquitous lie that “black lives” don’t “matter” to the police. “What do we want? Dead cops,” chanted participants in a New York anti-cop protest…. Cop-killer Ismaaiyl Brinsley, who assassinated NYPD officers Wenjian Liu and Rafael Ramos on December 20, 2014, exemplified everything the elites have refused to recognize as the antipolice crusade marches on: he was a gun-toting criminal who was an eager consumer of the current frenzy of cop-hatred.

The anti-cop bloodlust of this movement wasn’t satisfied then and won’t be satisfied now. We saw it last August in a Black Lives Matter protest at the Minnesota State Fair. As the Daily Caller reported and a video showed:

Black Lives Matter protesters marching on the Minnesota state fair on Saturday spewed violent anti-cop rhetoric just hours after a Harris County, Tex. sheriff’s deputy was ambushed and executed at a Houston-area gas station. “Pigs in a blanket, fry ’em like bacon,” activists with the St. Paul, Minn. branch of Black Lives Matter chanted while marching behind a group of police officers down a highway just south of the state fair grounds.

This inflammatory racial animus has been repeatedly stoked by grandstanding liberal politicians who benefit politically from perpetuating the culture of victimhood. Gun and crime researcher John Lott Jr. has noted President Obama’s contribution to the war on cops:

As a response to the police shooting of Michael Brown, President Obama proposes $263 million for police training and body cameras. But more police training wouldn’t have prevented the Brown shooting and the president’s proposal plays into the hands of those who blame the police. President Obama has continually undermined police departments around the country, and his demand for more training fits that pattern. In 2009, he jumped to the conclusion that Cambridge, Massachusetts police “acted stupidly” when they arrested Henry Gates. He personalized the Trayvon Martin investigation in a way that to many implied the murder was radically motivated. And yet again last week, he emphasized that the anger to the verdict was “an understandable reaction” and blacks’ distrust of police is “rooted in realities.” Nevertheless, whatever Obama implies, there was absolutely no evidence Officer Darren Wilson was motivated by race and he did exactly what he should have done. Brown’s robbery of the convenience store, his decision to reach into the police car and punch Wilson while trying to take his gun, and finally Brown’s decision to charge Wilson was what caused the teen’s death.

Unindicted co-conspirators in providing moral support in the war on cops is New York Mayor Bill De Blasio and Minnesota Governor Mark Dayton. Stoking the fans of racial animus, After the death of Eric Garner in a confrontation with police, De Blasio told of warning his mixed race son of encounters with police.

De Blasio, who is white, gave some details of the conversations he and his wife, Chirlane, who is black, have had with their 17-year-old son, who is a senior at Brooklyn Technical High School. “With Dante, very early on, we said, ‘Look, if a police officer stops you, do everything he tells you to do. Don’t move suddenly. Don’t reach for your cellphone,’” said deBlasio. “Because we knew, sadly, there’s a greater chance it might be misinterpreted if it was a young man of color.”

After a police-involved shooting during a traffic stop which resulted in the death of the black driver, Dayton played the inflammatory race card:

A suburban police officer who killed a black motorist likely wouldn't have fired if the driver had been white, Minnesota's governor declared, jumping into a suddenly reignited national debate over how law enforcement treats people of color….

"Would this have happened if those passengers would have been white? I don't think it would have," Gov. Mark Dayton said to a crowd that gathered outside his residence all day and night Thursday. Hours after Dayton's remarks, gunmen shot and killed five police officers and wounded six more amid protests in Dallas over Castile's killing and a second fatal police shooting of a black man.

It’s not easy access to guns, Mr. President, that killed five cops in Dallas. It’s easy access to hatred stoked by black activists and sympathizers in public office who see cops as racial predators and ignore the courage, dedication, and color blindness of those who show up every day to protect the lives of those that spit on them. The Dallas cops ran towards the gunfire that endangered citizens of every color and ethnicity. They have paid the ultimate price for the false mantra of those who run away from the truth. It’s not white cops versus blacks. It’s good guys versus bad guys.
