you yourself mentioned that situation where the sewer company was illegally working past the hours they were expected to work within. Where were the cops? Deliquient right? Good for the citizens for taking the matters into their won hands for the lack of said police force, by shooting at the transformer and hopefully shutting down their work schedule at all hours of the night.
What was so amazing is that the contractor figured out immediately what it was that enraged the citizens. No doubt he knew that before he decided to keep them awake.
BTW, the cops had been called to enforce the county's noise ordinance ~ dozens of people called them. After the shooting they probably thought it was just more people complaining about noise.
