Dont you think calling the cops would be a bust?

no i didn't threaten her with it although it was in my hand but she already called the cops and Im dodging them for now because i dont know what to say to them at this point. Should I deny the taser because their was another witness besides her boyfriend. I was hoping to say it was my way of defense by hitting her back and pulling out the taser but she called the cops so it kinda makes me look bad. what should I do I dont want to call the police now that its 3 days later it might be worse. Right now they dont know my last name or how to contact me, should I keep it that way?
