The settlers in the "New World" responded to the strict mercantilist policies of the British Crown by smuggling and taking part in illicit trade. The British would attempt to impose revenue laws, but it was unsuccessful until British authorities made use of writs of assistance (general warrants; allowed the bearer to seize any prohibited goods, and etc).
