Where did you git that information

i never reveal my sources

but since you asked nicely, here's where i came up with that:

prolepsis: The anticipation and answering of an objection or argument before one's opponent has put it forward. {AHD}

paralipsis: rhetorical device of emphasizing something by omitting it or mentioning it only cursorily. (DODW)

Thus, the AB's defensive arguments are obviated by the fact that in order to defend himself he would first have to identify himself as the AB ~ effectively requesting a directed verdict against himself (pardon the legal terminology).
