February 1970, The Weather Underground conducted their first two violent strikes against what they considered to be prime examples of American imperialism. The first attack occurred on February 16th at the Parks County Police station in San Fransisco. When at 10:45 P.M. a pipe bomb filled with nail shrapnel exploded on a ledge on the top floor of the station fatally wounding police sergeant Brain Mcdonnell and wounding 9 others. Although this attack could not be traced back to the Weather Underground, it’s still quite speculated that the organization was behind the bombing. In fact F.B.I agent Larry Grathwohl stated in a report that “there are irrefutable and compelling reasons that establish that Bill Ayers and his wife, Bernadine Dohrn, are responsible for the bombing.”

The Second attack of February 1970, occurred at the residence of New York supreme court justice judge John M. Murtagh. Murtagh at the time was ruling over the trial of “Panther 21” a case in which members of the Black Panther Party where allegedly plotting to blow up New York landmarks, and department stores. On the night of February 21st. a molotov cocktail was thrown onto Murtagh’s front porch, as well as on his car. In addition multiple windows of his home where broken, and spray-painted in red on the side-walk in front of his home where the words “Free Panther 21”, “Kill the Pigs”, and “The Vietcong have Won”. Although no one was caught or accused of the crime, it is speculated that the Weather Underground where responsible based on the decision and speculation of the last S.D.S conference in in December.
