True, but somewhat irrelevent..Take the extreme example: a system set up so sound travels unimpreded, but light must go through a large barrier than slows it down to below the speed of sound.
You'll now hear the blast, THEN see the shot. And this still doesn't violate cause and effect.

I think we're arguing different things. My point is that you can't violate cause and effect (and it seems you agree). Yes, you could contrive some situation where the light from the bullet was slowed to the point that you hear it before you see it (so in this case, I agree with you). You could also just close your eyes while the bullet was firing, then you'd never see it. That's the problem with using the term "speed of light". So just to be clear, when I say "speed of light", I mean the speed of light in a vacuum (which is the speed that information travels at).

A gun that shoots teleporting bullets would violate causality, since the bulletes would effectively be travelling faster than the speed of light. The victim would be shot, then later see the gun firing (we'll say that there is vacuum between the two people). The order of the two events would be changed in this frame. Causality requires that all observers observe cause and effect in the correct order.

You're confusing information with cause still. Both the bullet leaving the barrel and the sound are -effects-, not causes. Simiarlly, getting hit my the bullet is a effect. So is SEEING the bullet.
We've already established it doesn't matter what order you see the effects in. That was the point of the light-slowing barrier comment. In that scenerio, exactly the same thing happens- the observer sees the impact, THEN sees the shot. So, why does a FTC bullet violate causulity in a way this other example does not?
