Hahahahahaha.... Sucker.
You chose to tangle with the wrong nerd...
In that series, Year Two, Batman turns to the gun to defeat "The Reaper" who is a realy bad guy with sickles and guns for hands. In the entire series, which by the way is the only time I know of that Batman even picks up a gun voluntarily, Batman never shoots anyone. In fact, he teams up with his parent's killer and spends the whole time stopping him from killing anyone.
Here is my proof. Choke on it.
It starts well with this page... (click the image to make it big enough to read)
And so it continues on a course of cool with some interjections from the hippie authors...
Here's Batman NOT using his gun...
As you can see in the second panel, it is clearly strapped to him. Yet he uses his weak batarang thingys instead. So later, we see Batman tell the guy he is working with to try "his way" which is sans gun.
And just when you thought things couldn't get lamer... Batman goes off and pulls this crap in the next page...
What the hell was that?!?!?!! Then the criminal does something that makes sense...
Right... Good Job, Batman...
Then when the bad guy dies from falling off the building, Batman goes and chucks the gun.
So... Where's your Batman now?
Huh?
Batman is an anti-gun pansy, plain and simple.
