Joe Arpaio’s defense has been he unintentionally” violated the order, but had no intention of purposely violating the order. This would include things previously mentioned, along with: abuse of power, misuse of funds, improper clearance of cases, unlawful enforcement of immigration laws, and election law violations.
He has also referred to his tent jail as a concentration camp for prisoners, and to many, he seemed quite proud of that fact. Those who label themselves part of the Resistance Against Trump believes the American president committed a verifiable impeachable offense, despite Article II Section 2 of the US Constitution that gives a president unlimited to power to pardon anyone (possibly even including himself) for any federal crime except impeachable offenses.
These individuals praise Judge Bolton, and find Trumps pardon to be invalid because it offends the Due Process Clause. They claim through Arpaio’s term practically anyone who came to his jail had their rights violated; especially if they were in the inmate was a minority or Hispanic (and specifically after the 2011 injunction). This is also the belief of law professor Martin Redish, as noted in a New York Times article.
Whatever information the Trump Administration will present at the October hearing, people are still concerned about the 160 people who have died in Arpaio’s jail, and the lack of explanation or thought of consequences for the alleged abusive guards. The Arizona Central sees a very public legal fight over the horizon.
