But apparently it isn't murder if you kill your own clone, as Riker did in Up the Long Ladder, so at least there's a contractual loophole to get out that inconvenient implication.
Actually, it is, per one of the early DS9 episodes. The only difference between the two is that Riker's clone wasn't fully formed and conscious yet. If he had tried to kill Tom or if the UPLL clone had been walking and talking, it would have been murder, no questions asked.
