In the U.S they have been using a lighter method of this, where the cops will take your valuables if caught with them while traveling (most often cash by those using it for legal business such as conventions and trade shows) and then release the person with no charges. They love to target people who are from another state, knowing it increases their odds of the person being unable to sue them in court as it increase the financial hardship to do so. The I10 corridor here is famous for it.
