They are not being deprived of property -- they're being deprived
of the use of property until the case is settled. Big difference. But even that's changed with the new federal regulations.
The new asset forfeiture regulations are found here. A good summary of the changes are found here in PART II, about half-way down. Read to the end. It should address your concerns.
Thank you both for the links. It appears I have some reading to do.
