Playing Hitman: Absolution professionally requires a lot of stealth and planning. You scope out the scene, and land your kills in such a fashion that no one will notice.

Watch the live action video to see one scene, played out in the two different methods. Then pick your favourite. I'll go with idiot, because: chicken suit.
