I read all your posts. This is just my opinion, but rom what you wrote, I believe you went to the gun store to purchase the firearm because the first "buyer" was denied - that is rather clear and actually, none of your posts state otherwise. Your friend had more than "an interest" in the gun - he attempted to purchase the gun. Parsing words does not, I think, help your explanation.
Just as the first buyer was unaware and surprised by the denial, I am supposing you were surprised by the "straw purchase" law. Correct me if I'm wrong, but I'm supposing you went inside the store together, discussed his denial and in some fashion you said "well, since he can't buy it I will". This is, for better or worse, exactly the type of situation the straw purchase laws are designed to prohibit and I presume why the gun store owner denied the purchase. I would have done likewise.
