It's illegal, pure and simple. No need to sugar coat.
> "Police can seize cash that they find if they have probable cause to suspect that it is related to criminal activity. The seizure happens through a civil action known as asset forfeiture. Police do not need to charge a person with a crime. The burden of proof is then on the driver to show that the cash is not related to a crime by a legal standard known as preponderance of the evidence."
Cops in the story act like the mere existence of a lot of cash is probably cause. This is the opposite of one of the major reasons for law and law enforcement: to protect people's property. We have police so we can feel secure with our property, not to take it so we have to fight back for it.
