A、They are illegal drugs found in Los Angeles. B、They are cheaper goods sold overseas. C、They are copies of the original product

Hello, everyone. Thank you for coming. Today we will talk about a phenomenon that everyone of us here is familiar with—fake products. Fake designer clothing, medicines and other products are made and sold around the world. American investigators say the fake goods industry is bigger business than the illegal drug trade. And they say anyone buying such goods could be providing support to other criminal activities. Fake goods may look like the real thing. But they are only copies made without the approval of the business or individual with rights to the original products. Many fake goods enter the United States through the port of Los Angeles, California. People looking for low prices on goods go to a part of Los Angeles called Santee Alley. It is a place where fake goods are sold. Clothing, sunglasses, watches and toys fill the many small stores in the area. Police have repeatedly raided stores that carry fake designer goods. As a result, people who sell them are much more careful. Police officer Kris Buckner says they will offer buyers the fake goods, and then take them to a storage area where the fake goods are hidden. The estimated $500 billion a year counterfeiting industry is bigger than the drug trade. Street gangs, international organized crime groups and even terrorists are involved with counterfeiting. He says: "Then you have groups that have ties to Hezbollah, Muslim Brotherhood and Hamas that have engaged in this activity. The problem is it’s a perfect opportunity for these guys to make money. You got to look at the global marketplace. It’s estimated that 10% of the goods you’ll see out there are estimated to be fake. " At the port of Los Angeles, police seize fake clothing, prescription medications, electronics and cigarettes. Investigators say large amounts of the fake and stolen designer products enter through American ports in large shipping containers. More than fourteen million shipping containers arrive in Los Angeles every year. Police are able to inspect less than 1 % of them. Police say there are ways to tell if a product is fake. Look at the kind of store where the product is sold, and whether the price seems too low. If so, it is probably a fake.
