It is literally highway robbery, as it is the highway patrol pulling you over and stealing your money.
Nothing more than: highway robbery, is necessary. You're spot on, that's exactly what it is, and it's nothing more. It's robbery. Using any other names for it, just assists the police in covering up what they're doing through confusion. Everyone should begin calling it robbery by police or the equivalent, and stop referring to it as civil asset forfeiture in public forums (that's only useful in a technical/legal regard).
These are all language tricks used to manipulate the masses. "Double plus good" is not a stretch at this point if we become complacent to this kind of manipulation.
