The New Girl

"Who's your new friend there?" I asked Olivia. She looked back at the new girl who she had made friends with and smiled sweetly at me.
"Oh I wouldn't even think about going near her." She couldn't be that bad if she had good looks. Right?
"And why is that?" I ask. She seems to think about what to say then says in return:
"Because she's grab a cop's gun kind of crazy." She replies.
