or she idk (insert gender)

I'd choose anything that was silent and precise but I think there exists silencers for guns so you just need that and a precise gun

That works also, you'll never have witnesses. You can snipe 'em from a roof of a building or tree.

You'd have to put the bullet with a glove before!

Right, no fingerprints!
