On Sunday, April 23, a friend of McVeigh’s in Michigan told reporters that McVeigh believed the government had implanted a tracking chip in his “rear end [so] the all-seeing eye of the government could keep an eye on him and know where he was.”10 The same day, April 23, the FBI received a call from Linda Thompson, an Indianapolis attorney, militia spokesperson and producer of an underground documentary, Waco: The Big Lie, which advanced a theory that the government had deliberately set the fire that killed the Branch Davidans.
