Okay, he seems to be a joke of a character that was in a couple of stories in Batman 3 (the original 1940 version, not the DCnU series) as a foil for Batman and Robin.
But since the Gotham City Police Force still seems to need some regular characters, it would be interesting if maybe Snyder or somebody latched on to this guy and re-invented him.
Any thoughts or comments? And does anybody know if he actually made any appearances after those two stories in Batman 3? (I checked www.comics.org, but those two stories were the only ones thay had for a character named McGonigle related to Batman stories.)
