As we've already discussed here, ever since the murder of a San Francisco woman by a criminal immigrant who had been deported five times over the weekend, Fox "news" has been on a roll, defending Trump on just about every show on their network for his remarks about Mexican immigrants.

Media Matters has compiled a list of some of them, and I'm fairly sure they missed quite a few, along with some information refuting Trump's claims:

Study: Crime Rates Higher Among Native-Born Americans Than Immigrants. A 2013 study in Criminology and Delinquency found that "first-generation immigrants commit crime at a lower rate than second-generation and native-born, non-Hispanic whites," as ThinkProgress explained. The Pew Research Center created a chart showing the study's results:

Northwestern University: "Essentially No Correlation Between Immigrants And Violent Crime." Northwestern University professor Jörg L. Spenkuch used nationwide FBI crime statistics and records from every county in the US and found that there is "essentially no correlation between immigrants and violent crime," according to a 2014 article.

Study: Incarceration Rates For Young Men Lowest Among Immigrants. According to a study by the Immigration Policy Center, a division of the American Immigration Law Foundation, the incarceration rate of men aged 18 to 39 was five times higher for the native-born population than for immigrants:

Among men age 18-39 (who comprise the vast majority of the prison population), the 3.5 percent incarceration rate of the native-born in 2000 was 5 times higher than the 0.7 percent incarceration rate of the foreign-born. [American Immigration Law Foundation, Spring 2007, via Media Matters]

Bill O'Reilly was the latest to jump on the Fox bandwagon defending Trump during his Talking Points Memo this Monday night. Here's transcript of Bill-O's latest screed from his blog: The Vilification of Donald Trump Over Illegal Immigration:

Does the truth hurt?

Or did Mr. Trump unfairly malign Mexico and millions of Mexican illegal aliens?

Talking Points will now answer those questions.

The primary mistake Donald Trump made in his campaign kickoff speech was speaking too generally about the border problem.

Most Mexicans who sneak into the USA or overstay their legal visitation status do so because they are economically deprived. They are largely under-educated folks who are trying to feed their families.

Also, the vast majority of illegal aliens do not commit crimes while on American soil, apart from their immigration offense.

But there are big problems stemming from Mexican illegal immigration, and the statistics tell the story.

As we all know, Mexico is the major supplier of illegal drugs to the USA. The drug cartels down there have corrupted the police and many politicians.

They are brutal thugs who commit mass murder, torture and generally shame their nation.

ISIS has nothing on these drug cartels; they are both savage enterprises.

The government of Mexico is not capable of defeating the drug lords and rejects direct American intervention.

U.S. drug agents are not allowed to carry firearms in Mexico, thereby putting themselves at great risk assisting Mexican authorities.

For decades Mexico City has allowed organized crime to brutalize its own people and Americans, as well.

Some of the drug organizations have branched out into people smuggling, charging money to get desperate migrants across the border.

In the process many, perhaps most, migrant women are sexually molested, and that was the rape situation Donald Trump mentioned.

But it's not ordinary Mexicans doing the raping. It's the gangsters, and Trump should have made that clear.

The truth is there is little supervision on the Mexican side of the border. Cities like Juarez and Nuevo Laredo are literally run by the drug cartels.

Border security in Mexico is non-existent and has been for decades.

That situation will not improve.

So Trump is correct in saying that only a massive wall will stop the chaos. And even then, drugs and people will get through, although not to the extent they do now.

Washington knows all this but has turned away from securing the border ever since President Reagan promised to do so after he signed an immigration amnesty in 1986.

Mr. Reagan did not keep his promise, and every single president since has failed to secure the southern border. Every one.

Now what about the immigrants themselves?

Fifty-nine percent of Mexican residents and illegal aliens have less than a high school education.

Only four percent have a college degree.

Sixty-eight percent are poor or near poor.

Fifty-seven percent receive means-tested welfare of some kind.

Fifty-six percent do not have health insurance. Many of those will receive Obamacare subsidies.

So, Trump's analysis is correct. The majority of Mexicans coming to the USA are not achievers in the economic sense.

To be fair, that was the case with the Irish, Italian and European immigration waves of the past … hard-working people trying to improve themselves.

But here is the dangerous part.

According government statistics, 71% percent of non-American citizens in federal prisons are from Mexico. Colombian nationals are second, just 4%.

Mexican criminals represent a whopping 16% of all convicts serving time in federal penitentiaries.

That is a huge burden on the American taxpayer, and a dangerous situation for ordinary Americans like 32-year-old Kate Steinle.

Last Wednesday Kate was walking with her father in San Francisco when she was shot dead on the street for absolutely no reason at all.

Police say 45-year-old Francisco Lopez-Sanchez, an illegal alien from Mexico, murdered Kate.

Apparently Sanchez has seven felony convictions and had been deported five times.

Yet he was still walking around the streets of San Francisco.

That's because Mayor Ed Lee and the eleven members of the San Francisco City Supervisors refuse to cooperate with the federal government on criminal aliens.

The feds asked the city of San Francisco to keep Sanchez in custody; the city refused. Ms. Steinle paid for that irresponsible and unconstitutional decision with her life.

San Francisco is a sanctuary city, and violent crimes committed by criminal aliens have happened before.

City authorities refuse to say how many because they know this is a huge scandal -- a black mark on the history of San Francisco, the most tolerant of cities.

The family of Kate Steinle is asking for calm, not vengeance.

But Talking Points is not as charitable.

In 1996 President Bill Clinton signed the Illegal Immigration Reform and Responsibility Act, which stipulated that local and state authorities were to cooperate with the feds in apprehending illegal aliens, especially criminals.

In 2007 then Mayor Gavin Newsom issues an Executive Order stating that as a Sanctuary City, San Francisco would not cooperate with federal authorities on illegal immigration matters and would protect even criminal aliens.

The feds did nothing.

In 2010 the Obama administration openly said it would not punish cities that refuse to obey the 1996 law.

So here's the deal.

The mayor and city supervisors of San Francisco are directly responsible for the death of Kate Steinle and the Obama administration is complicit.

Attorney General Loretta Lynch could order FBI agents to arrest Mayor Lee and the supervisors for violating federal law. She is within her authority to do that.

I know that will never happen because racial politics drives the law these days, which is why Trump caught so much hell.

The Constitution demands that the federal government protect Americans from foreign intruders.

Obviously, that responsibility is not being met. And if you point that out as Trump did, you are a racist, a piñata for the open-border crowd to bash.

The fact that a felon could be deported five times and still be walking around the USA should shame Congress.

Where is a law that says if you are deported one time and come back you serve five years in prison. Where is that law?

Congress should pass it, and if President Obama doesn't sign it, everything will then be on the table.

That legislation should be called the Kate Steinle law, much like Jessica's Law.

So who will sponsor the new law? Please let me know. We are looking for some legislators of courage. Are you out there?

Talking Points is disgusted with the cowardice of our elected officials, from the crazy left San Francisco people to the president to the Congress.

Most of them are rich folks who could not care less about the violence and chaos out of control criminal activity south of the border is creating here.

If Mexico does not crack down hard on border intrusions and drug trafficking, we should punish them economically. Period.

This entire disaster has been going on for far too long.

The excuse that America is at fault because we use drugs and do not secure the border on our side is valid.

We are at fault.

But that does not excuse Mexico's rampant corruption and abuse of its own people.

Drug and people smuggling injure millions and cost lives. It's the dirtiest of crimes.

Finally, the poor people sneaking in here to paint your house are not the problem.

The cowardly politicians who will not uphold the law and the Constitution of the United States are the problem.

That's what Donald Trump should have said.

And that's the memo.
