Immigrant crime: the fallacy of composition and the Usual Suspects

Neighbor (after reading a letter to the editor): "Aren't you afraid Russell Pearce's henchmen will come to get you."
Gilligan:  "No ... they should be afraid of me [and if not me ...  my uncle, Louie, The Greek].  The only person I'm afraid of is Keyser Soze."

"Do undocumented migrants commit more crime proportionally than native-born Americans? No."  
-- Ed Montini, AZ Republic, 1/10/19

Comrade Professor Montini, King of the Nibelung:

What's your source for this observation?  The Cato Institute, i.e., Landgrave and Nowrasteh?  Their study focused on incarceration rates, a dubious proxy for crime.

Landgrave and Nowrasteh found in their study of those they called "illegal immigrants" that "illegal immigrants are less likely to be incarceratedthan native-born Americans."  Lott, on the other hand, using a 100 percent sample of Arizona incarcerations found that illegal immigrants were over-represented,  criticizing those (e.g., Landgrave and Nowrasteh) who relied on the American Community Survey sample (ACS).   Lott study raises the pertinent issue of African-American incarceration rates and African-American recidivism rates skewing overall incarceration rates for the native-born.   Lott, to the extent he did, might be guilty of a fallacy of composition where he suggests Arizona data extrapolates to the entire US.

Disaggregating  Landgrave and Nowrasteh's findings shows that they are not inconsistent with Lott's, however,  since Arizona has a relatively small African-American population and the likelihood that Arizona's African-American population may not suffer as much from institutions and institutional status (in an Ayresian sense) as African Americans do in other parts of the US.   According to Landgrave and Nowrateh,  Hispanic Americans of any race, illegal immigrants and not, have higher incarceration rates than White and Asian Americans.  Lott, for his part, attributes differences in native-born Hispanics and Whites to the well-known association of youth with crime and allows that but for that demographic native-born White and Hispanic crime rates are about the same.

Why are African American incarceration rates so high?  1) The institutional inheritance, old and new.   2)  The Usual Suspects:  in criminal investigations the police first look for known culprits: mugshots, fingerprints, DNA.  

But, facts don't really matter here, Ed.   This wall business is just a political pissing contest.   Even if the wall accomplished nothing,  the lousy $5 Billion isn't worth shutting down the TSA and Coast Guard ... a rational opposition would trade the wall for something they believe is worthwhile.

Suggesting that facts matter is dissembling on your part, Ed.   You either don't understand the study you cite or you don't care ... probably both.   You just want to be part of the pissing contest.   You get up in the morning and without even changing out of your pajamas, you start throwing BS at the wall.   You're an embarrassment to all the people in your professor who work hard at putting together stories that are interesting and bear some semblance to reality.  You, Ed, are guilty not only of the fallacy of composition, but also, the fallacy of division.

The Wall and the Spitfire

"But data from his own administration repeatedly show that a rising number of smuggled drugs, especially more potent ones like heroin and cocaine, are increasingly seized at legal ports of entry, which are not impacted by a wall."  -- AZ Republic, 1/8/19

We don't need a wall because we catch the most smuggled drugs at ports of entry?   This brings to mind how the British decided where to armor their Spitfire fighter planes during WWII.  Fighters need to be light to be fast and maneuverable.   When you want as little extra weight as possible, where do you add the armor.   The British put their crack operations researchers to work and gathered data on bullet holes.   When they were done and presented their data to the Royal Air Force, a young pilot shouted:  "Eureka!   Put more armor where the most bullet holes are."   The old professor leading the operations research team quietly shook his head and then spoke:  "No, young man, that is not where to put the armor.  The planes with the bullet holes all came home safely.   We need to put the armor where our data shows there aren't any bullet holes.  Where our data shows no bullet holes is where the fighters were shot that didn't come back."   Because we are catching smugglers at one place, doesn't tell us that there isn't smuggling where we're not trying hard to intercept it and, therefore, have no data, ie, bullet holes, about the incidence of smuggling in those places. 

Thank God, they didn't let "journalists" design the Spitfires.

Times and AZ Republic cover up their Irish problem and other mistakes

In his spirited column about the New York Times and Alice Walker's anti-Semitism, Richard Cohen complains that the Times refuses to admit a mistake, interviewing Walker and not being shocked by her bigotry.  He just discovered that?  The Times fired their mistake department back in 2017 and even when they had a Public Editor some "mistakes" were off limits, eg, "OP-ED mistakes are not within the purview of the Public Editor."

Some years ago OP-ED columnist Bob Herbert wrote an egregious, error-filled column that blamed Irish immigrants who [allegedly] refused to fight to free poor blacks for the New York City draft riots.   Herbert neglected the part about the commanding generals at the pivotal Civil War Battle of Gettysburg being  Irish Americans,  George Gordon Meade and John Reynolds.   He also left out the part about New York City's Irish Brigade committing mass suicide on the eve of Emancipation while storming the stonewall at Fredericksburg,  12/13/1862.   In fact, the people who incited the riots were Americans with perfectly American pedigrees.  The one immigrant who was part of the upper-class cabal opposing Lincoln wasn't Irish.   The Times has never apologized for Mr. Herbert's nativist column or even published a letter of complaint.

Likewise,  the Times has never addressed it's problematic interview with James McPherson where it failed to challenge McPherson on the nativism and anti-Catholicism in his Battle Cry of Freedom and For Cause and Comrades,  where McPherson claimed immigrants were skulkers who gained "inglorious visibility" through late war enlistments.  How did the Times and Professor McPherson miss the part where immigrants won a quarter of the Civil War Medals of Honor and that these awards are highly correlated with enlistments, indicating a high immigrant presence in the Union army and navy throughout the war -- immigrants from literally all over the world.

The Times isn't alone in refusing to acknowledge mistakes.   The Arizona Republic has the same flawed blind spot.   It too endorsed Professor McPherson and his Battle Cry of Freedom and casually published Clarence Page's nativist column that blamed the Irish and their gangs for slavery not going away by itself.  Apparently Mr. Page believes that without immigration the South would have never seceded and there wouldn't have been a Civil War where the Meades and Reynoldses won the biggest battle.   No apologies from the Arizona Republic or Mr. Page.

The Man Who Never Returned

"People in the West don't understand how easy it is to get around [without a car]."  
-- Transportation expert, quoted by Linda Valdez, AZ Republic, 12/21/18

I did my time on the LIRR going to graduate school and work, a mind-numbing experience.   My grandfather organized the Boston Carmen's Union (and picked Felix Frankfurter to arbitrate during the big strike).  It seems like every other person in my neighborhood is from New York ... some of the neighbors even have siblings born in the same hospital as me or who went to my high school.   My next door neighbor went to the same college as I did in Massachusetts.  It takes us as long to get to the T station near grandma's house near Boston as it does for me to drive to downtown Phoenix.   Lots of people in the West have a really good understanding of what it's like to get around without a car and how mind-numbing it can be now to travel in Boston and New York.

The rail systems in New York and Boston were built decades ago when there was no minimum wage and health care benefits, and bargaining for a five day work week was a big deal ....  Good luck to those who want to replicate those rail systems elsewhere in an era when the elves have to be paid a living wage.

Good luck to private private investors who want to build a railroad to Tucson from Phoenix ... but what travelers in the West really need is another lane on I-10 and/or a surtax on all the trucks headed to California that clog I-10's lanes (let's call it a carbon tax). 

BTW:  there was a time when a 10-year-old girl (ie, my mother) could be handed five dollars and be sent to downtown Boston via the MTA with her little sister to buy shoes (and the elves lived in triple-decker tenements).   "If you have a problem find a policeman."  Would anyone in their right mind do that today ... not in Boston and certainly not Phoenix ... when to find a policeman you dial 911 and have to wait 30 minutes to an hour for the cop to show up.  We're going to grandma's house for Christmas ... Uncle Paul's loaning us a car to get around when we get there.

Nollaig Shona!

These are the times that try men's souls
In the course of our nation's history the people of Boston have rallied bravely whenever the rights of men have been threatened
Today a new crisis has arisen
The Metropolitan Transit Authority, better known as the M.T.A.
Is attempting to levy a burdensome tax on the population in the form of a subway fare increase
Citizens, hear me out, this could happen to you!
Well, let me tell you of the story of a man named Charlie
On a tragic and fateful day
He put ten cents in his pocket, kissed his wife and family
Went to ride on the MTA
Well, did he ever return?
No he never returned and his fate is still unlearned (what a pity)
He may ride forever 'neath the streets of Boston
He's the man who never returned
Charlie handed in his dime at the Kendall Square station
And he changed for Jamaica Plain
When he got there the conductor told him, "one more nickel"
Charlie couldn't get off of that train!
But did he ever return?
No he never returned and his fate is still unlearned (poor old Charlie)
He may ride forever 'neath the streets of Boston
He's the man who never returned
Now, all night long Charlie rides through the station
Crying, "what will become of me?
How can I afford to see my sister in Chelsea
Or my cousin in Roxbury?"
But did he ever return?
No he never returned and his fate is still unlearned (shame and scandal)
He may ride forever 'neath the streets of Boston
He's the man who never returned
Charlie's wife goes down to the Scollay Square station
Every day at quarter past two
And through the open window she hands Charlie a sandwich
As the train comes rumbling through!
But did he ever return?
No he never returned and his fate is still unlearned (he may ride forever)
He may ride forever 'neath the streets of Boston
He's the man who never returned
Pick it Davey
Kinda hurts my figers
Now, you citizens of Boston, don't you think it's a scandal
How the people have to pay and pay?
Fight the fare increase, vote for George O'Brian
Get poor Charlie off the MTA!
Or else he'll never return
No he'll never return and his fate is still unlearned (just like Paul Revere)
He may ride forever 'neath the streets of Boston
He's the man who never returned
He's the man who never returned
He's the man who never returned
Et tu, Charlie?
