Common phenomenon, similar to "mansplaining," except when done by a pig (police officer) trying to explain away their bad and usually racist behavior.
Cop enters home and arrests black homeowner (in his own home). Cop later realizes his mistake and tries to explain away his racist behavior by saying that said homeowner was acting suspiciously.
