This was fun to explain to my kids at breakfast today. Their ears perked up at the name Martin because they are big Redwall fans.

If you're following the #UNL #statistics saga (proposed for elimination based on bad stats), you might find the seminar we gave yesterday interesting... youtu.be/fUk2R0UYWpA

It was weird to rail against someone for an hour, but strangely cathartic, and the #datavis seems to have been effective?

To prep for the higher ed policy class on censorship next week, I'm rereading Schrecker's No Ivory Tower. Buddy this intro has it all! SCOTUS jumping on the bandwagon, disregard of first amendment rights, why congressional hearings played such a key role, how private companies aided the government.
Screenshot of page 3 that reads: McCarthyism: The Anatomy of an Inquisition By February 3, 1960, Joseph R. McCarthy had been dead for nearly three years, and the novement that had received his name was presumably over. But not for Chandler Davis. On that day, Davis, a former instructor of mathematics from the University of Michigan, ended a six-year struggle against McCarthyism, said goodbye to his family, and surrendered to a federal marshal in Grand Rapids to begin serving a six-month prison term. Davis's crime had occurred on May 10, 1954 when he refused to tell the House Un-American Activities Committee (HUAC) whether or not he had ever been a Communist. Davis challenged the committee, insisting that its questions about his politics infringed upon his freedom of speech and, as he put it, overstepped "the bounds placed on Congress by the First Amendment.'" He knew that he would probably lose his job and be convicted for contempt of Congress, but he hoped that the Supreme Court would eventually exonerate him. Instead, on June 8, 1959, the Court in effect ruled against him in the similar case Lloyd Barenblatt, another former college teacher who had also defied HUAC on First Amendment grounds. The 5 to 4 decision affirmed that the committee did not violate its witnesses' constitutional rights by asking them about their relationship with the Communist Party (CP). That ruling sent both Barenblatt and Davis, whose case was determined by Barenblatt's, to Danbury Federal Penitentiary. Screenshot of page 7 which reads: Most of this housecleaning took place at congressional hearings. Legislative investigations gave the conservatives a perfect arena for their campaign against the New Deal and its supposed sympathy for Communist subversion. To begin with, as congressmen constitutionally immune from lawsuits, they could make accusations without having to worry about being sued for libel. In addition, since legislative investigations were not judicial proceedings, these politicians could use witnesses whose testimony did not have to stand up in court. Best of all, committee hearings created headlines. American politics had never offered a more dramatic spectacle than the confrontation between the investigators and their witnesses, especially when those witnesses pulled microfilms out of pumpkins and talked of false names, clandestine meetings, secret passwords, and the arcane workings of a shadowy underworld peopled by Soviet agents and urbane upper-class spies. Once the rise of Richard Nixon showed how a smart politician could parlay his berth on an investigating committee into the Vice Presidency, congressmen clamored for such positions. In 1952, 185 of the 221 Republicans in Congress applied for seats on the House Un-American Activities Committee, an unpopular assignment only a few years before. Screenshot of page 9 which reads: McCarthyism was amazingly effective. It produced one of the most severe episodes of political repression the United States ever experienced. It was a peculiarly American style of repression--nonviolent and consensual. Only two people were killed; only a few hundred went to jail. Its mildness may well have contributed to its efficacy. So, too, did its struc- ture. Here, it helps to view McCarthyism as a process rather than a movement. It took place in two stages. First, the objectionable groups and individuals were identified-during a committee hearing, for example, or an FBI investigation; then, they were punished, usually by being fired. The bifurcated nature of this process diffused responsibility and made it easier for each participant to dissociate his or her action from the larger whole. Rarely did any single institution handle both stages of McCarthyism. In most cases, it was a government agency which identified the culprits and a private employer which fired them.

Yesterday, Stephen Miller questioned details re 170+ Americans detained by immigration agents.

“Abject lies,” he wrote.

Here’s the thing: We tracked, catalogued, and compiled every one of those 170+ cases.

Because...we do our homework.
