As a 30 cop I have seen the focus shift from catching dopers with drugs to snatching money and property. To prove a drug case you need evidence that proves the charges beyond a reasonable doubt. To snatch the money/property one only needs to show a preponderance of guilt. Simply being caught with a large sum of cash makes you guilty. The IRS tactic of grab the money, and argue later is now common in law enforcement. The property owner has to prove his innocence. This is just wrong.
Not under federal law.
