Hire another person to hire another person to smuggle in an illegal sniper rifle from a Russian army surplus store. The buyer will give the rifle to the first guy, who will kill him. Then he kills my target. I pay him with a million (counterfeit) dollars inside a briefcase linde with plastic explosives, which explode exactly 2 minutes after I hand it off to him, killing him, and destroying the sniper rifle.
I've given too much thought to this.
