A gun

She points a gun at you! It could be a fake gun, but you're not sure.

"Now I caught you red handed. I had to see how far you would go, but now I have all the proof I need to turn you in, you dirty pervert."

She get's up and walks some steps closer to you, her gun still pointed at your chest.

"Now release one of the girls, and I know she'll be glad to call the cops."
