How far would the missed shots from laser turrets in Star Wars travel? Will we one day be inundated by a barrage of stray laser turret blasts from a long ago, far away intergalactic war?

For clarity: Star Wars was just for the sake of an easy example. I recognize that there are numerous other, more SCIENCE-fiction-y films, books, etc that could be used in place, but Star Wars was the easiest for the sake of this question.

Also, I'm aware of the hypothesis of the origin of gamma ray bursts being from some intergalactic war before the origin of these was discovered. I was hoping to get some further expansion on this subject.

No, don't worry. The energy dissipates over distance/time. After only a few thousand miles (in which time it would be very unlikely that a stray laser blast would hit anything given the relative emptiness of space) the energy would have spread out over such an area to be (mostly) harmless.
