I am going to pretend that your question was meant as a joke and simply laugh. LOL
Nope. I was serious.
If plugging your EV into an outlet without permission is considered stealing, then why isn't taking a drink of water from a drinking fountain?
Both water and electricity are utilities that must be purchased by the school district.
Neither one is supplied free of charge.
So, if the cops in this story are so worried about someone 'stealing' electricity, why aren't they equally diligent about people 'stealing' water?
