2. On May 4, 1970, members of the Ohio National Guard fired into a crowd of Kent State University demonstrators, killing four and wounding nine Kent State students. The impact of the shootings was dramatic. The event triggered a nationwide student strike that forced hundreds of colleges and universities to close. H. R. Haldeman, a top aide to President Richard Nixon, suggests the shootings had a direct impact on national politics. In The Ends of Power, Haldeman (1978) states that the shootings at Kent State began the slide into Watergate, eventually destroying the Nixon administration. Beyond the direct effects of the May 4, the shootings have certainly come to symbolize the deep political and social divisions that so sharply divided the country during the Vietnam War era
