Any good prosecutor could convict her of several felonies and gross misdemeanors...
She left the scene of an attack that ended in an otherwise justifiable self-defense shooting without reporting it to the police.
She attempted to cover up a homicide.
She tampered with the scene of a crime.
She failed to report a felony to which she was a direct witness.
She discharged a firearm within city limits. (misdemeanor in most jurisdictions, but a felony in a few)
This ad is the sort of thing that, although darkly humorous to "insiders", will be latched onto by the "antis" as an example of how all lawful carriers behave, and will be used against us all in the "court of public opinion"...
I'd be looking for a new training company if this is how they train their students to behave after a self-defense shooting...
