This article highlighted the one of the many unforeseen dangers in our modern lives that we don't think about. I've never really thought about public USB charging ports, even NYU's new Mercer building has them filled with spades and I've used them without a second thought.
Indeed, @sirbobthemarvelous really gives an insightful though on this topic, which closely related to our life. We should all think about this and take actions to protect us and call for further regulation. --- Comment from Xiyu Hao (xh2187)
