and the incursion into Cambodia. As a show of sympathy for the dead students, Mayor Lindsay ordered all flags at City Hall to be flown at half mast the same day. Brennan organized a rally of construction workers to show support for Nixon's Vietnam policies and American soldiers fighting in Vietnam. At 7:30 a.m. on May 8, several hundred anti-war protesters (most of them high school and college students) began holding a memorial at Broad and Wall Streets for the four dead students at Kent State. By late morning, the protesters—now numbering more than a thousand—were demanding an end to the war in Vietnam and Cambodia, the release of "political prisoners" in the U.S., and an end to military-related research on all university campuses. At five minutes to noon, about 200 construction workers converged on the student rally at Federal Hall National Memorial from four directions. At first, the construction workers only pushed but did not break the thin line of police. After just two minutes, however, the workers broke through the police line and began chasing students through the streets. The workers selected those with the longest hair and swatted them with their hard hats. Attorneys, bankers and investment analysts from nearby Wall Street investment firms tried to protect many of the students but were themselves attacked. Onlookers reported that the police stood by and did nothing. A postal worker rushed onto the roof of City Hall and raised the American flag to full mast. When city workers lowered the flag to half-mast, the construction workers stormed City Hall, overwhelming the police. Deputy Mayor Richard Aurelio, fearing the building would be overrun by the mob, ordered city workers to raise the flag back to full mast. The construction workers then ripped the Red Cross and Episcopal Church flags down from a flag pole at Trinity Church. They then stormed two buildings at nearby Pace University, breaking windows with clubs and crowbars and beating students. More than 70 people were injured, including four policemen. Six people were arrested. President Nixon held an emergency press conference to defuse the situation before tens of thousands of students arrived in Washington, D.C., for a protest rally on May 9. Many organizations claim that Peter Brennan provoked the construction workers into action. At least one eyewitness described two men in grey suits using hand signals to direct the construction workers during the riot The
