g.h. changes history to suit themselves.

ITA...I don't even think many people even cared that it was Laura, since it was written as self-defense.
Laura isn't on the canvas, and GH doesn't care about exhonerating her...Genie on the other hand may have told then that she would not be back unless they cleaned up that mess.
For all we know Helena may have killed Rick.
But as you said, it is the writers story. They will write it to suit the staff comings and goings. Years later they may rewrite it again. That is just the way they do it!
