content: The matter is that someone did something they weren't supposed to and the sockets are clearly marked not for personal use. As for the claim about power surges potentially frying connected equipment(edit: equipment of users, not the train), if it did then costs and subsequent disorderly people could be worse then being strict and making sure people see that there are consequences. Also, if I steal 1 piece of candy in a store costing maybe 1 or 2 cents am I not a thief? Suggesting the cost is negligible isn't an excuse, given the amount of trains and sockets there could be a very real bill. Now it would've been tactful to give the man a warning instead of arresting him, then again the police arrested him again after they released him because of his behavior, so probably he did a lot of this to himself. It was his attitude that screwed him over, not the system imo.
