"Who knows how OOC Batman will be after coming back from being "dead" and killing someone with a gun? I'm hoping that it'll all be glossed over, personally." Bah! I've wanted Batman to carry a gun again for years! (Why yes, I am a Mike W. Barr fan.)
Seriously, though, I think Grant M. was going for the idea that the gun was an extraordinary measure for an extraordinary situation, & that Batman would adapt to that situation--not that this would change Bats from this point on.
You know what this means? Despite the fact that I call him "word salad boy," I support Grant Morrison's on Batman more than that of Alan Grant or Denny O'Neil, or even :gasp: Chuck Dixon.
Then again, Alan Grant & Denny O'Neil, blllaaaaargggh.
