First it was the infamous Duke rape case. Then it was Trayvon Martin’s death, followed by Michael Brown’s being shot six times and left lying dead in the middle of the street in Ferguson, Missouri. Lots of protests and riots, but, in the end, the truth came out in court in all three cases.

Now, here we go again: one police officer in Baltimore acquitted, five to go. Chalk up another learning lesson for the Black Lives Matter crowd. Except for one problem: They don’t learn. And the reason they don’t learn is because they aren’t interested in the facts if those facts undermine their fictitious narrative that police get up every morning with the aim of hunting down and killing unarmed black men.

Those who push this absurd narrative could care less that it flies in the face of the facts. What these ill-intentioned folks really want is to throw out the legal-justice system and punish those whom they believe to be guilty of committing crimes. Perhaps they would be more at home with Sharia Law?

How well I remember the Trayvon Martin-George Zimmerman case. As the facts were presented night after night on television, it became clear early on to any objective viewer that it was Zimmerman, not Martin, who had been the victim of a life-threatening attack.

This isn’t to imply that George Zimmerman is a Boy Scout. He’s not. But personalities aside, the fact — and it is a fact — is that he was merely doing his job when he followed Trayvon Martin on the night of Martin’s death.

When it comes to incontrovertible evidence, the cuts and blood on the back of Zimmerman’s battered head were analogous to the discovery of O.J. Simpson’s Bruno Magli shoes. It was hard to draw any other conclusion than Martin had attacked Zimmerman and was banging his head against the concrete sidewalk. Unfortunately, what Martin discovered the hard way was that such aggression tends to get one shot.

No one talks about the fact that had Zimmerman not taken lethal action, Trayvon Martin might very well have killed him. A human being can only take so many blows to the back of the head, and there’s no reason to believe that Martin was going to stop banging Zimmerman’s head against the sidewalk any time soon.

So once again the victimization crowd got it all wrong. Nevertheless, to this day, Trayvon Martin is seen by millions of misinformed folks as a martyr who was killed in cold blood. So much so that Horrible Hillary plans to once again meet with Martin’s mother when she campaigns in Florida. The woman is a professional panderer beyond shame.

The Ferguson tragedy was even worse. While the Black Lives Matter rabble rousers immediately created a totally false narrative about what had happened on that fateful day in Ferguson, even giving a violent 300-pound bully the nickname “Gentle Giant,” early on the facts revealed that Michael Brown had robbed a convenience store shortly before his run-in with police officer Darren Wilson and that his own violent actions caused Wilson to kill him in self-defense.

In a nauseating display of sticking his finger in the wind and politicizing the tragedy, Missouri governor Jay Nixon quickly went on TV and started babbling about “justice for Michael Brown’s family.” Not justice for the policeman whom Brown had violently attacked — justice for the criminal only.

But, in the end, the evidence was so crystal clear that in the most toxic environment imaginable, officer Wilson was acquitted. Even the DOJ publicly stated that there was no evidence to suggest that Wilson was guilty of any wrongdoing. It was pretty hard to come to any other conclusion, given that at least seven African-American eyewitnesses testified that Michael Brown had violently attacked officer Wilson and was coming at him again, full speed, when he was brought down by a hail of bullets.

Finally, there’s the mysterious death of drug dealer Freddie Gray in Baltimore, which led, as usual, to violent riots. The District Attorney, Marilyn Mosby — a rank amateur who had never before tried a case — began with a news conference where she dropped jaws by telling the crowd, “This is our moment” and promised justice for — you guessed it — Freddie Brown’s family. Again, not unfettered justice, but justice for the alleged criminal. Nothing like an impartial prosecutor giving a political speech in lieu of quietly doing her job.

From the beginning, Baltimore was a no–brainer, even more so than the Michael Brown case. There was zero evidence that any of the six officers had intentionally harmed Freddie Gray, and, in fact, no evidence that the injuries that led to his death were even incurred while in police custody.

As I’m sure millions of other people (including law professor Alan Dershowitz) did, I predicted early on that all six police officers would be acquitted, so the acquittal of officer Edward Nero this week was no surprise to me. The other five officers who were indicted in the case will almost surely be acquitted as well, assuming that the verdict is handed down by a judge rather than a jury, as it was in the Nero trial.

Let’s get one thing straight: No civilized person wants to see anyone — particular young people — killed by police. That’s a given. But the Black Lives Matter movement is a total fraud that is hurting, not helping, the black community. Blaming police, or anyone else, for killing a black person in cold blood when the facts clearly show otherwise is reprehensible.

What is most disturbing is that this myth harms the very people whom Black Lives Matter claim to be concerned about, because police in major cities have become less and less willing to take action to protect citizens in black communities. Based on what they’ve witnessed in places like Ferguson and Baltimore, they have good reason to be concerned about becoming targets of criminal investigations themselves.

But perhaps the worst problem of all is that this black-lives-matter fakery diverts attention from the biggest threat young black men actually face today — black-on-black crime. Approximately 90 percent of all black homicide victims are murdered by other blacks. That, dear reader, is a fact.

Thus, black-on-black crime is the real problem that needs to be addressed, and in a serious, aggressive fashion. The claim that police officers are the biggest threat to black men — particularly young black men — is a complete ruse. The truth that the professional race baiters will never talk about is that only about 4 percent of blacks killed in 2015 were killed by police.

An even more eye-opening statistic is that over the last decade, the chances of a police officer getting killed by a black person were 18.5 times greater than the chances of an unarmed black being killed by a cop. In other words, the narrative that young black men are being hunted down and killed by police is not only a lie, it’s 180 degrees removed from what is actually happening!

If, as I suspect will be the case, five more acquittals are handed down in the Freddie Gray case in Baltimore, it will be time for people with public platforms to start going after shameless frauds like Hillary Clinton, Bill de Blasio, and others who have been shamelessly promoting racial division and spreading lies about a fictitious epidemic of police killing unarmed black men. No such epidemic exists — period.

Poll after poll has shown that what law-abiding citizens in black neighborhoods really want is more police presence, not less, and it’s time for influential blacks to step up to the plate and convey that message to the low-information public. Shame on those who continue to spread the big lie about police hunting down unarmed blacks with no interest whatsoever in the facts.
