Thanks for the ping! I'm just catching up on the day's discussion now and I didn't catch how the Weather Underground Organization got into the thread, but I will mention that the WUO and Halperin were both linked to IPS back around 1970, and IPS and the Tides Foundation both have received funding from the Samuel Rubin Foundation (which relates to the "Shadow Party" funding network being discussed on the other thread).
Also, the M.O. of targeting military installations emulates what the antiwar movement was doing in the early 70s. One thing the FBI's files on the VVAW mention is that the VVAW joined other antiwar groups in an effort to collect information on "the military-industrial complex".
Thank you for the ping, Fedora! I haven't been here much lately and had even missed the Indymedia raid linked on this thread!
