Two things to note: first, the Missouri HP may need to

be a bit more careful with their training materials:
COLUMBIA, Mo. | A new document meant to help Missouri law enforcement agencies identify militia members or domestic terrorists has drawn criticism for some of the warning signs mentioned.

The Feb. 20 report called "The Modern Militia Movement" mentions such red flags as political bumper stickers for third-party candidates, such as U.S. Rep. Ron Paul, who ran for president last year; talk of conspiracy theories, such as the plan for a superhighway linking Canada to Mexico; and possession of subversive literature.
One question here: what do they define as 'subversive literature'?

Second, Bill Ayers is a chickenshit coward:
It’s been quite a turnaround for Bill Ayers. The Communist terrorist who planned bombings of police stations, in order to inflict maximum injury and death on police officers, is now depending on the police at the University of Illinois, where he is a “distinguished” professor, to protect him from the tough questions of students' parents. In fact, one parent who presented Ayers with a Bible and a copy of Ayn Rand’s Atlas Shrugged was arrested last Thursday night and charged with the curious offense of somehow interfering with university affairs. A visibly-nervous Ayers accepted the books but quickly placed them down on a table.
...
According to Lt. Roy Acree of the University of Illinois at Urbana-Champaign Police Department, parent Mark Thompson was arrested on a charge of “interference with a public institution of higher education” because of his activity at the Ayers lecture. Ironically, the statute (720 ILCS 5/Art. 21.2 heading) was passed "in recognition of unlawful campus disorders across the nation," which is precisely what Ayers and his comrades in the Students for a Democratic Society were doing on college campuses in the 1960s.
Translation: "He made Ayers uncomfortable, so we arrested him." I say that because
Acree told AIM that Thompson had said that he figured his actions would get him arrested, and that he apologized to the police officers who arrested him later. Still, what did Thompson do that broke the law?

“I wasn’t there,” Acree said, although he did watch the incident on YouTube. “I felt like at that time that Thompson was at the point of interrupting the speaker, who was an invited guest of the university, and was preventing the speaker from speaking.”

But the video seems to show that the meeting was breaking up at that point.
