Very true.You aren't missing anything. Some people like to create their own version of events and pass it off as facts.
Then again, some events can be "spun" to two different and equally plausible versions of the same event.
This case could well include elements of the above. What is known is that Morales came out of her home holding a weapon and waving it around (bad idea).
The rest, however, can be spun into two different versions:
Spun version A.
Responsible biker comes close to being injured by a reckless lane change. He gently admonished the other person to be more careful. She responds by hitting his bike and then leaves the scene of an intentional accident. He and some new friends follow her and advise her to stop as the police have been called. They then attempt to converse with her about the accident as she enters her home. She then emerges with a weapon.
Spun version B.
Biker is recklessly blazing down the road and is cut off. He flies into a rage at the other driver. The other driver pulls next to him, but does not hit him or the bike (no damage to either one). He then yells at her again. Frightened, she leaves. Biker and new friends start to chase her. Biker then starts yelling at her as she enters her home. She then enters the home and emerges with a weapon.
In this case, the Biker gets to tell his spin. Morales, however, cant. There is no easy solution to that difference.
