Yup, sounds like she was trying to scare the girl. She was mad at the kids and wacking them before this. Jackass didn’t even check to see if there was a round in the chamber not that they should be aiming guns at people and pulling the trigger.
I wonder if there were powder burns and a muzzle imprint on the kid, that would show if the gun was pressed against her. I wouldn’t trust anything they say at this point anyway.
