Jen your girl did the exact right thing by keeping her wits, but do not give her a handgun until she's 21. She can take a shotgun to work but not a pistol.
A camera if there's a "next time" and bear spray in case Stiffler decides to get out of the car.
Oh, and talk her out of dousing someone with hot coffee unless it's self-defense otherwise she'll be the one facing assault charges.
All very good advice. A pistol cannot be CC by anyone under 21.
