Phone Trail to Oklahoma City
For instance, Kirk Lyons, radical attorney for neo-Nazi causes (and for Andreas Strassmeir), has admitted that his office received a lengthy call from Timothy McVeigh the day before the bombing. Significantly, that telephone call does not show up in the phone records this magazine has obtained.

McVeigh said they bankrolled the bombing in part with the November, 1994, robbery of Arkansas gun dealer Roger Moore. "Mr. McVeigh stated that he laid out the plan and that Terry Nichols alone broke into Moore's house and stole the weapons," a report says.
In case anyone is keeping score, Roger Moore was likely a government informant, as well.
