Final answer:
During the Vietnam War, there was often significant conflict between student protesters and police officers, highlighted by events such as the Kent State shootings.
Step-by-step explanation:
The relationships between student protesters and police officers during the Vietnam War are best described as often being in conflict. The late 1960s and early 1970s were marked by a significant antiwar movement, with protests growing in size and intensity as the war dragged on. One of the major student organizations that spearheaded these protests was the Students for a Democratic Society (SDS). High-profile incidents, such as the tragic shootings at Kent State University, where four students were killed by the Ohio National Guard, underscore the severity of the conflict between protesters and law enforcement.
