 It's hard to say what sort of training he may have had, but certainly, you know, someone didn't just go out and buy a rifle of this type this afternoon. My guess would be, and it's simply a guess, that it is someone who had, you know, developed some sort of a skill set, had probably practiced, gone to a range, and, you know, all of that will be figured out later on. But to have this kind of an incident, to take this kind of a shot from this kind of distance, would indicate to me that it's somebody that's very familiar with the firearm.
