Accidentally backed into a car in a parking lot, lady went psycho.

So, I hit her car, and walked over to apologize. She saw my Colorado plates and screams I'm calling the cops! Hope you can pass a drug test! I say of course (haven't done anything but caffeine in over 7 years) then she blocks me in and gets so heated that I just lock myself in the car and wait for the cops. When they get there she screaming at them to give me a sobriety test and I offer to take a breathalyzer test just to assausage her anger. Cop shines his flashlight in my eyes and asks me a few questions then gives me a paper and sends me on my way. They kept her there because she wanted to follow me... shoulda stayed home.
