But I didn’t remember that the last time was specifically during the Selma-to-Montgomery March in March 1965. I was reminded of this this morning by a piece in NOTUS.

A federal judge ruled that the march was protected under the First Amendment and that the state was responsible for ensuring its safety. Wallace refused to use state police power to do that, thus deliberately forcing Johnson’s hands (Johnson was pissed), figuring that he would gain politically if federal troops got into violent in encounters with anti-civil rights counter-protestors.
