To rebunk is to successfully rebuke a "debunking," often retractions
made under duress or thrown up to save face by PR departments or
information officers, as well as
news agencies.
"Here we are at the site of a mostly peaceful protest. It is not violent." -- Newscaster
"Yeah they ended up having
ten arrests and assaulted about a
dozen people as well as tried to
cement the police station shut. They rebunked the riot." -- Random guy
