Shipwreck shows Roman Smuggling?

Six months ago a Roman era shipwreck was recovered by archaeologists from the shore near Trapani. Among the finds were jars containing a range of food and drink, including olives, fish sauce and wine. But they also found a large number of 'fictiles', tubular tiles were interlocked and were used in building. These were commonly smuggled into Rome from North Africa, where they could be bought at a quarter of the price, and so experts have concluded the Trapani ship was also engaged in smuggling. MSNBC has some great photos, and quotes from experts.
