Weird, I searched an online comic shop and that had no results for "Officer Down!" as a paperback, so I thought it wasn't available. But I found it on amazon in both an US and an UK edition, so thanks for the heads up.

I mean, in general I tend to favor single issues over trade paperbacks for collecting US comics, but in this case getting that paperback will cost only about one fourth of getting the old single issues, judging based on prices I've seen.
