Hypothetically returning fire during the Aurora massacre

I read an interview with Ted Nugent wishing that someone in the theater during the Aurora massacre had a gun so that he or she could have returned fire and saved a lot of lives.  In response to one of Nugents' comments, I thought back to the 1980s when I was researching a paper on Star Wars/SDI/Missile Defense back when President Reagan was focusing on stopping Soviet ICBMs from reaching the US. Some pro-SDI people had opined that the technology needed to make the moon landing a success was similar enough to what would be needed to stop ICBMs that the task would be a pretty simple one. The critics (that I very much agreed with) pointed out that the moon wasn't disguising itself, wasn't taking evasive action and wasn't shooting back. None of those conditions would hold true while trying to stop ICBMs. I thought of that as I read Nugent's statement:

Last week my wife Shemane and I were filming a segment for our Spirit of the Wild show and we were shooting at watermelons surrounded by human silhouette targets just as kind of a competition and from 20 feet and from 20 yards and we were shooting from every imaginable angle, under cover, from sitting, from squatting, from prone position, from behind cover and from in the open, and we never hit an innocent and we never missed the watermelon. And I'm just a guitar player. If a guitar player can neutralize a watermelon from 20 feet -- and this is with live fire, by the way.

To which my reaction was "Okay, you and your wife were in a perfectly safe, leisurely situation, in broad daylight with no distractions, all the time in the world and absolutely no danger. So what does your situation have to do with anything?" Keep in mind that the alleged attacker James Holmes was wearing body armor, came in by surprise and started shooting, the dark theater was immediately filled with screaming people scrambling wildly, trying desperately to get out of the way.

In other words, Nugent's situation of neutralizing watermelons in a leisurely, unhurried manner had absolutely nothing in common with the situation faced by the people in Aurora, Colorado.

And by the way, Nugent tries to present the AR-15 rifle as a mere sporting implement, but as one can see by this picture thread, that particular model of gun was a weapon of war that soldiers used back during the Vietnam War. The AR-15 was not a toy and wasn't merely a hunting rifle.
