On an evil fantasy

We have an emergency announcement system in our town. There is a siren and then a computer generated voice comes on and says something like “this is a test of the emergency announcement system”. The speakers must be gigantic, because it is very loud and seems to come from everywhere at once. I have this fantasy about accessing the computer files that store the announcements.

(Loud Siren)
I see what you’re doing there. Have you no shame? Yeah, you there... in the car. Stop that right now!”

I bet you could hear the screeching car tires in the next state.
