Others, however, have suggested that these arguments are specious. Former Weather Underground member Mark Rudd admitted that the group intended to target people prior to the accidental town house explosion. "On the morning of March 6, 1970, three of my comrades were building pipe bombs packed with dynamite and nails, destined for a dance of non-commissioned officers and their dates at Fort Dix, New Jersey, that night." Grand juries were convened in 2001 and 2009 to investigate whether Weather Underground was responsible for the San Francisco Police Department Park Station bombing, in which one officer was killed, one was maimed, and eight more were wounded by shrapnel from a pipe bomb. They ultimately concluded that members of the Black Liberation Army were responsible, with whom WUO members were affiliated. They were also responsible for the bombing of another police precinct in San Francisco, as well as bombing the Catholic Church funeral services of the police officer killed in the Park Precinct bombing in the early summer of 1970. Ayers said in a 2001 "New York Times" interview, "I don't regret setting bombs". He has since claimed that he was misquoted. Mark Rudd teaches mathematics at Central New Mexico Community College, and he has said that he doesn't speak publicly about his experiences because he has "mixed feelings, guilt and shame". "These are things I am not proud of, and I find it hard to speak publicly about them and to tease out what was right from what was wrong."
