Good thing we know Grandpa Joe has no trouble surrounding himself with people who will willingly break the law for him.Daddy's problem is that: (1) even his pals aren't totally willing to perjure themselves; and (2) there is lots of documentation and audio recordings.
Bobulinski is mostly selling the proposition that his testimony (smoke) supports the inference of something meaningful (fire).
Jeezus you are not good at this.
