No. You've explained why YOU THINK it is not relevant. Your (mistaken) opinion doesn't mean Marina's statement is irrelevant to others.
Feel free to make a case for its relevance, when
everything else about that incident is considered.
It is a FACT that Marina said that she saw a rifle in the blanket. You just don't understand. Slow down.
Actually it's not. It's a fact that Ilya Mamantov claimed that Marina said that in his translation.
But let's say that the translation was accurate. Then it's also a fact that Marina
said that Lee worked at a place on Hines, Lee
used to have a rifle in Russia, and that the rifle he had was a dark gun.
So what?
