Fake Avastin Wholesaler: 'We Followed Protocol'

Like a sheriff tracking a poacher in the Wild West, the hunt for the source of counterfeit Avastin is sending sleuths - federal investigators and journalists - in numerous directions (back story). One outpost that has yielded some insight is Barbados, where Tom Haughton is based. A Canadian, he runs several foreign distributors that have sold Avastin into the US.

Haughton has spoken previously with journalists, although this CBS News clip gives you a chance to see for yourself how he explains his role in this mess. Not surprisingly, he insists that he followed the protocol for distributing medicines, and he says the problem may rest with the 19 physician practices in the US that purchased the fake supplies.

"I have nothing to hide," he tells CBS. "The businesses that I have are ethical, safe and legal... We followed protocol... We, as a licensed registered UK wholesaler, bought the product through the trusted and controlled EU supply chain... We are legally entitled to sell any products, with our license, to any registered or licensed doctor, wholesaler...These clinics, they purchased this product, and we're not in the US. So I'm not sure what the US laws are. They would have to make sure what they're doing."
