Ditto.
Like James mentioned, the guy was not "jailed" for stealing electricity... he spend several hours in a cell while he was being booked/processed. He was not convicted and jailed for theft.
And yes, the value of what he "stole" (if that's the correct word, which I believe it is) may be trivial, if we say hey, stealing a little is ok... then at what point do we draw the line?
Is it ok to take someone else's electricity to charge your car for 20 minutes? Is it ok to charge up for a few hours? Overnight? At what point does it go from being "ok" to stealing? Is it ok for me to pull into my local gas station and top off my tank for free? Hey, I only needed a gallon... it's trivial. Is helping myself to five gallons ok? Ten?
And his excuse for making what he did ok by saying it's just like taking a drink from the school's water fountain is bogus. The school installs water fountains so that students, staff and visitors can drink from them. The school didn't install an electrical outlet for this guy to help himself to it and charge his ecomobile.
