&gt; They&#x27;re essentially saying that no one has a legitimate cause to hold thousands of dollars in cash, so they must be doing something illicit, so we have cause to take it.<p>Think about it statistically. The standard is &quot;more likely than not&quot; the money is obtained illegally. If you pull over 100 people with large amounts of cash, what percentage obtained it illegally? If it&#x27;s greater than 50%, then you can always seize the cash under that standard. You don&#x27;t need to make the judgment that no one has a <i>legitimate</i> reason to carry that cash, just the weaker judgment that it&#x27;s <i>statistically unlikely</i> that the cash is legitimate.
