The January Foreign Corrupt Practices Act (FCPA) sting operation that nabbed 22 gun-industry executives–21 of them arrested at a Las Vegas trade show–changes the white-collar defense landscape markedly. The bust was the result of a classic undercover operation, complete with elaborate ruses, false identities and the key collaboration of an executive who was caught and flipped.

But as law enforcement escalates its war on FCPA crimes and expands its repertoire of tactics, white-collar lawyers are left with fewer options for defense.
