Six People Arrested In Terror Plot

They wanted to go on a shooting rampage at Fort Dix in New Jersey, kill as many soldiers as they can. Thank God they were caught and kudos to all those who help catch them.

They were Islamic radicals, but at least three of them were of Balkan descent...White Eastern European...so this makes me think of a few questions;

1.) They wanted to shoot soldiers, is that necessarily a terrorist attack and if so, does that qualify Virginia Tech as an act of terrorism? What's the difference, because it's Muslims doing it? Also, the target was soldiers, not civilians, which makes me think of what Israeli Foreign Minister Tzipi Livni said recently;
"Somebody who is fighting against Israeli soldiers is an enemy and we will fight back, but I believe that this is not under the definition of terrorism, if the target is a soldier."

2.) Some of them were American citizens who have Second Amendment Rights to own a gun. They were caught trying to obtain AK-47's, which are difficult to obtain in New Jersey because of strict gun control laws. Does the NRA still think these guys should still have the right to own a gun...any gun, including an AK-47?

3.) My reasoning against Racial Profiling is that it doesn't cover all potential terrorists. Sure, most of them are going to be foreign Middle-Eastern or South Asian looking men, but these guys were not, at least the three from Europe. They look like European, they are white. Racial Profiling wouldn't have worked here, would it now?
