From a legal framework point of view, the US is there already. It probably isn't as blatantly abused. Make no mistake, if you attract the ire of an aggressive prosecutor, you can and will be charged with some sort of serious crime.
Another angle in the US is are situations where you cannot be charged with a crime, but your property can. For example, if you are travelling on an airplane with a "large" quantity of cash, the authorities can (and have) essentially "arrest" your cash via asset forfeiture. You have rights, but your property does not.
