When Sheridan is reviewing the footage that she captured of Paige and Phoebe on her camcorder, it is clear that the video being played is the clip from the show, not how the recording would look from her specific location.
If the Cleaners can eliminate the phantasm from the video recording to protect magic and the Charmed Ones, why couldn't they keep in the robber using a gun against Morris thereby the killing would be self defense and not murder.
