No, a statement is not evidence no matter how much you want it to be. A _sworn testimony_ of a _witness_ is evidence. But there can't really be any witness here

No, a statement is not evidence no matter how much you want it to be. A _sworn testimony_ of a _witness_ is evidence. But there can't really be any witness here, unless the person on the other end was extremely careless. So you get a bunch of hot air and unsubstantiated allegations which will never go anywhere.
