> "Money laundering" (however that is defined) should not be a crime. Theft, fraud, etc. should be.
This goes back to this weird fetishism where people think it was oh-so-cool to arrest and convict Al Capone for "not paying taxes" instead of convicting him for his actual crimes.
A society which thinks its cool to send people to jail for tax evasion instead of sending them to jail for organized crime is a failed society.
