The Idiot in Charge unsurprisingly pardoned an elderly racist asshole, Arpaio was just the tip of the iceberg when it comes to talking about the Prison Indusrial Complex.
What’s hidden behind the walls of America’s prisons

Some may have heard that there are about 2.3 million people behind bars, but that figure tells only part of the story. Yes, in a stunning array of 1,719 state prisons, 102 federal prisons, 901 juvenile correctional facilities, 3,163 local jails and 76 Indian Country jails, as well as in military prisons, immigration detention facilities, civil commitment centers and prisons in the U.S. territories, we physically contain more human beings than any other country in the world. In addition to those actually locked up, there are another 840,000 Americans being supervised on parole and an additional 3.7 million people being monitored on probation.

100 million Americans have a criminal record, it's insane.

The article is well worth a read, Arpaio's self described concentration camps were hardly sickeningly unusual.

How are there so many prisoners?

In 2012 the U.S. penal population was 2.23 million adults, the largest in the world, with an incarceration rate of 707 per 100,000. That year, nearly 25% of the world’s prisoners were held in American prisons, yet the United States constituted just 4.5% of the global population, according to the U.S. Census Bureau.
“During the 1980s, the U.S. Congress and most state legislatures enacted laws mandating lengthy prison sentences — often of 5, 10, and 20 years or longer — for drug offenses, violent offenses, and ‘career criminals.’ In the 1990s, Congress and more than one-half of the states enacted ‘three strikes and you’re out’ laws that mandated minimum sentences of 25 years or longer for affected offenders. A majority of states enacted ‘truth-in-sentencing’ laws requiring affected offenders to serve at least 85% of their nominal prison sentences.”
“From 1980 to 2000, the number of children with incarcerated fathers increased from about 350,000 to 2.1 million — about 3% of all U.S. children. From 1991 to 2007, the number of children with a father or mother in prison increased 77% and 131%, respectively.”
“Among white male high school dropouts born in the late 1970s, about one-third are estimated to have served time in prison by their mid-30s. Yet incarceration rates have reached even higher levels among young black men with little schooling: among black male high school dropouts, about two-thirds have a prison record by that same age — more than twice the rate for their white counterparts. The pervasiveness of imprisonment among men with very little schooling is historically unprecedented, emerging only in the past two decades.”

The Prison Industrial Complex

The raw material of the prison-industrial complex is its inmates: the poor, the homeless, and the mentally ill; drug dealers, drug addicts, alcoholics, and a wide assortment of violent sociopaths. About 70 percent of the prison inmates in the United States are illiterate. Perhaps 200,000 of the country's inmates suffer from a serious mental illness.

One thing that is highly noticeable whether it be a Democratic Party or Republican Party lead
government this industry marches on unabated, prison rape is treated as some kind of joke, as a justifiable part of the punishment even.

We are stronger on crime is often the rallying cry at election time, whatever the fuck that actually means.

Arpaio is just part of the problem, but mainly that honour goes to our successive governments
from the respective Presidents right on down to the local sheriffs.

Our solution has always been to deal with the fallout from our governments neglect rather than to actually try and solve our societies basic flaws/problems.

Greed is good when it is used by the Oligarchs otherwise it's a sin for everyone else.

Just a thought
