This is excellent, but I really wish people would stop putting these "projection in mid air" into concepts. It's best to project forward on current tech. Such technology isn't even something that's being worked on at this point.
Hannah, people do horrible things to others. There is a drug war raging in Mexico between two cartels trying to control the country. They did it, most likely, as revenge against the rival cartel as the woman was associated with the rival in some way. The war in Mexico must be stopped. Atrocities like this happen on a daily basis and the United States continues to turn a blind eye to the situation.
