The search warrant affidavit, which was under seal until a month after the raid in a likely attempt to avoid media scrutiny, relied solely on a confidential informant who made the claim that weapons were being shipped to 951 Iglehart using the U.S. Postal Service. In a sensationalist move, the police also tried to tie property owner Michael Whalen to a defunct 1970s political group, the Symbionese Liberation Army, in order to bolster the warrant’s outrageous claim of arms shipments. However, once inside 951 Iglehart, police discovered that the boxes contained only vegan literature. Unsatisfied, police broke through a locked attic door to enter the neighboring but separate 949 Iglehart, which plaintiffs claimed was the operation’s true objective.
