The government (police) can take your property at any time if suspicious, even if you are innocent.
The burden is on you, not them, to do something about getting a court to look at it.
If you do nothing, they keep your property, your money; and you lose; without any court or judge ever even seeing the case.
If you want to do something about it, you need cash for a lawyer and court filing fees. The law provides the government a free lawyer and requires them to pay no court filing fees.
The police agency that targeted you and took you down gets to keep 70% commission on the cash, valuables, your vehicle they seize from you. Could this affect their honesty about their investigation; or, the appearance of propriety?
