This is just legalized theft. Those items they stole will then be sold off themselves and the police keep the money.
It would be a shame if the government decided to classify Bitcoin as illegal tender to take advantage of the asset forfeiture strategy, seize A ish load of coins just to have most of the assets then to turn it around and decide to legalize it just like they did Or do with gambling laws. Difference but jus saying hw the "law" can quickly change for whatever reason. That would be a *itch move on their part because they can easily operate their own mining farms and what not.
They probably wont make it illegal but if you try hide your finances in bitcoin they'll likely just confiscate your physical wealth instead.
