Some comments/notes made as I read through and research the NSBA letter.
Re: Federal Assistance to Stop Threats and Acts of Violence Against Public Schoolchildren, Public School Board Members, and Other Public School District Officials and Educators
Dear Mr. President:
On behalf of our state associations and the more than 90,000 school board members who govern our country’s 14,000 local public school districts educating more than 50 million schoolchildren, NSBA appreciates your leadership to end the proliferation of COVID-19 in our communities and our school districts. We also appreciate recent discussions with White House and U.S. Department of Education staff on many critical issues facing public schools, including threats school officials are receiving.
Footnote 9 links to two articles. The first states that "Police are investigating a man who flashed a Nazi salute and chanted “Heil Hitler” during a raucous Birmingham Board of Education meeting over a mask mandate for students." The second article states that Grand Ledge school board had to go into recess twice during the meeting. Once because someone went over their 3-minute time limit during public comment, and refused to sit down. The second time was after public comment, when two board members were speaking to one another and the audience kept interrupting. Hence, the footnote supports that an individual yelled a Nazi salute at one meeting but not two.
Here's the actual letter
