And saying "I don't know anything about this" is equivalent to saying "I don't know where my gun was when my aide came into possession of it".
Even these two statements would be contradictory. How can you read both meanings into that one sentence.
How is it not possible to read "I don't know anything about THIS" where "THIS" means "the commission of a crime"? Just what would Webb know about the commission of this crime?
I can explain it to you, but I can’t understand it for you.
