However, Palmer didn’t just stumble upon the lion: According to Zimbabwean authorities quoted in the
Independent, he allegedly bribed wildlife guides $55,000 for the honor. And a federal law called the Travel Act forbids foreign travel with the intent to engage in certain “
unlawful activities” overseas. One of those activities is
bribery. If Palmer traveled to Zimbabwe to hunt exotic species, and planned to bribe guides if necessary to access his prey, that offense would fall within the broad scope of the Travel Act. Palmer could be prosecuted in America for it.
The second way to make Palmer answer for his alleged crimes would be to extradite him to Zimbabwe to stand trial there. That would be a fairly simple affair. The United States has a generous
extradition treaty with Zimbabwe, which contains a “dual criminality” clause. Under the treaty, if an American commits an act in Zimbabwe that is illegal under both American and Zimbabwean law—and which is punishable by more than one year in prison—America is “obligated” to extradite him to Zimbabwe (and vice versa). Palmer’s potential violation under the Travel Act is punishable by up to five years in prison under U.S. law; his alleged bribery is punishable by
many years in prison in Zimbabwe. His crime thus fulfills the “dual criminality” requirement of the treaty, and America must extradite him to Zimbabwe if the government so desires.
