The drug business has a very distorting effect on a lot of businesses. For example, if the drug dealer owns a shoe store as a front, he can affort to sell his shoes cheaper and still make money.
When he sells the shoes cheaper, it drives the honest shoe stores out of business. Pretty soon, many business people have to become involved in the narcotics trade or go out of business.

why even bother to bring the guy to US? For a show trial?
The only thing that's going to happen is that another ruthless but smart guy is going to take over the drug trade in Columbia. The only way to win the drug war is to decrease the demand for drugs, and I don't see that happening soon.
