In the United States, property forfeiture laws effectively make the ‘protection’ of their vaunted constitution meaningless against seizure of pretty much anything, as various arms of the state can help themselves to property without the owner having ever been convicted of a crime and often without even being charged with one.
Alas this tyrannous state of affairs can now be found in Britain as well, at least when it comes to HM Customs and Excise. The fact that just on the opinion of a customs inspector that you have too much alcohol or tobacco for personal use, the presumption of innocence can be swept away, reversed in fact, and your property stolen by the state without you ever being convicted of smuggling. Without so much as setting foot in a court of law, if the representative of the state says you are a criminal smuggler, then you must prove otherwise on the spot or not only will he take the goods you are trying to bring into the country but he will also appropriate the vehicle in which you are transporting them, i.e. your car or van. You are guilty unless you can prove otherwise.
There are many things to admire in the USA that Britain should seek to emulate… however its legal system that allows convictionless theft by the state just on the say-so of state functionaries is not one of those things.
