Criminal prosecution of the owner because he decided that running cocaine was the best way to finance his company.

He was set up. He successfully argued entrapment, and was acquitted:

I said prosecution, not conviction.

He was entrapped, but he certainly said yes to bankrolling a cocaine smuggling operation, there's a recording of that event. While that was enough to escape conviction, it still cost him money and reputation at a time when he couldn’t afford it.

Asking for a friend, so you're saying this is a bad way to finance a company?
