If the premise of this cover is that Batman would be reluctant to wale the bloody tar out of a blind dude, I ask you to recall an earlier post where I listed the number of burn victims and slim women among his rogues gallery. Batman would dropkick five babies just to clear enough room to round-house punch a pony. Dude has no qualms, blind guys.
Favorite part of this cover, by the way: The black cat. Oh yeah, this is what they mean when they talk about black cats being unlucky, just like the old saying goes "See a black cat, blind guys will crock you en masse..."
