It's extremely difficult to control - even grazing an object the wrong way with your finger can end up breaking it into pieces. Giving someone a hug can easily end with you covered in blood from the person you just split in two.
The US has informed Russia of suspected upcoming terrorist attacks, under a “duty to warn” policy. Iran, too. Whether that information was sufficient or useful, we have only the State Department’s word, but it is still worth noting.
I actually got a somewhat decent education on it. Learned about unionization, the fight for weekends, battle of Blair Mountain, and the teacher even played “Solidarity Forever” in class.
I fully recognize my experience isn’t standard, though.
