That's why I specified that I was refering to the speed that photons travel at. Light
appears to move slowly through certain materials, but the individual photons still move at ~3x10^8m/s. In these cases what's happening is that photons are constantly being absorbed and reemitted, which makes the light appear to be moving slowly.

"Finally, let's say I run towards you arbitrarily close to the speed of light. I still see the gun go off first. There is nothing that I can do, as an observer, to witness you being hit by the bullet before the gun goes off."
Say you have a gun that teleports the bullet to the target on firing. The target doesn't see anything, the bullet hits, and then a while later they see the flash, and hear the report.
This does notviolate cause and effect! The bullet was still fired before it hit..its exactly the same as seeing the hit then hearing it.

Teleportation is science fiction.
