When Laura's lawyer speaks to her on the phone, she says that the court date to make the Restraining Order permanent is set for Thursday, but in actual fact, the court date was set for Wednesday, February 17, 1988, which assumedly was nullified by the massacre that occurred on Tuesday. February 16, 1988.

When Laura's boyfriend gives her the gun he tells her to fire all nine shots into Richard and states that no court in the world would convict her if she shot him on her own property. This is not good advice. While state laws vary about protection of self and property, one can use only the necessary force to stop an intruder (which simply brandishing a weapon might accomplish). If Laura shot Richard nine times, this could be seen by the court as unnecessary and unreasonable force, and it would make a claim of self-defense difficult. Shooting him one time would be self defense. Nine times is murder.

After Laura is shot, she goes out into the hallway and leans her back against a mural on the wall, and the cameraman is reflected in the glass of the mural.

When Richard corners Laura outside the office building after her tires are slashed, the camera is reflected in the glass door after he enters the building.

When Richard exits the motor home and is about to enter the office building to go on his rampage, at least three crew members are reflected on the back of the car in the foreground.
