Re “Trump Pardons Ex-Sheriff Seen as Migrant Foe” (front page, Aug. 26) and “A Pardon for Arpaio Would Put Trump in Uncharted Territory,” by Martin H. Redish (Op-Ed, nytimes.com, Aug. 24):

President Trump’s egregious pardon of Joe Arpaio, the former Arizona sheriff, despite concerns expressed by several political pundits and constitutional scholars, including Mr. Redish, is yet another example of Mr. Trump’s scant regard for established processes and protocols. The pardon is also a slap in the face of the judge who had held Mr. Arpaio in contempt of court and was yet to sentence him.

By repeatedly attacking Congress, the courts and the media, Mr. Trump is showing how little he knows about the Constitution and how our system of government works. Either a stern judicial reprimand or a congressional censure or both might be necessary to disabuse Mr. Trump of his autocratic tendencies.

To the Editor:

As a longtime resident of Arizona, I am appalled that President Trump has pardoned Joe Arpaio, the former Maricopa County sheriff. The damage that Mr. Arpaio did to this state and to this community is incalculable, and he did it by flouting not only the law as set down in the Constitution but the law of human decency as well.

It became a common sight to see his deputies harassing Hispanic-looking people for no other reason than their appearance. The result was not only to terrorize that segment of our community, but also to worsen racial tensions.
