The "speed of light" is represented by the letter c, because it's actually not the speed of light, it's the speed of causality. We can't observe light going faster than that limit, because we'd be seeing the effect before the cause. In short, FTL travel doesn't break causality as a side effect, you'd have to break causality to do any FTL travel.
