A Night to Remember

You sneak to the corner of the room where Katie doesn't see you. You quickly pull out your phone and dial 911.
"911 whats your emergency," the receptionist questions.
You explain, "My friend Katie has been dropping harmful drugs into peoples drinks and i'm worried how many people she will hurt."
"We will be there in about ten minutes," the receptionist assures.
"Thank you so much," you quickly add before hanging up the phone.
Ten minutes go by and the police arrive and you meet them at the door. You show the cops a picture of Katie so they know who to find. They immediately spot her and place her under arrest.
