One of the things we've been working on in our office is learning empathy. So we take the characters in an incident narrative, reverse/flip all persons/locations and then see how it changes our perception of the incident. So in this example, if we reverse everything, it becomes: "An Indian man shouting "Get Out Of My Country" in a bar shoots and kills two promising young American engineers working in India.". The effect that has would naturally be to make Americans afraid of going to or being in India, hence: terror alert, terrorism. So I can empathize and understand why the author of the article described the murderer as a terrorist.
