I am old enough to remember when President Eisenhower brought in Federal Troops to protect students when they integrated Little Rock, Arkansas high school. It was a horrible scene and Ike showed leadership by bringing in troops to stop the riots and protect the students. I wonder if Biden will show the same moral leadership with the current situation.?
The "troops" were federalized national guard, not regular army. And they were sent to enforce federal civil rights legislation to integrate the local schools. Protecting the Little Rock Nine was just a fringe benefit of the military's involvement in integration. It was the right thing to do, or Ike risked allowing states to run all over federal law.
This is completely different. There is a safety factor, of course, but there's also a free speech component that everyone from the presidents of the universities to the local law enforcement agencies are having trouble understanding - let alone allowing and encouraging. They don't seem to realize that free speech stops when the person threatens another, or trespasses, or defaces public property. I don't have any issue with the encampments - "sit-ins" are a long standing tradition in this country; however, the first person that has a sign with "Hammas' next target" with an arrow to Jewish students should be spending time in jail.
