Why the heck doubt it that things like this happen? To do so assumes they are perfect, which they are not, it assumes we are perfect, which we are not, and I can assure you the Chinese boat knew it was shadowing a US boat. they do it, we do it and the Russians and the Britts and the Indians and on and on.
Yes, I doubt it. I apologize if my not thinking like you makes you angry. Work on that.
