Discussion Topic: Should Billionaire Be Prosecuted for Helicopter Hunt?

Houston billionaire Dan Duncan admits he shot a moose and a sheep from a helicopter in Russia five years ago. He assumed the guided hunt was legal. What he can't understand is why he's being investigated for it here. From Reuters:

_Hardin expressed astonishment at the investigation in Texas by a U.S. prosecutor involving an event in Russia. The applicable law could be a 107-year-old law intended to stop international trafficking in rare plants and animals, he said.

"What the hell is the U.S. interest in bringing felony charges here for hunting on Russian soil, where not one single person has complained?" Hardin told the [Houston] Chronicle. "Is this really the best use of our prosecutorial resources?"_

What do you think? Is it?
