Hatfield McCoy:
Unseen, Hatfield shakes his head in disbelief. "Of all the ignerent crap, the dipsticks are pulling a crime surrounded by representations of vigilantes."
Walking boldly up to the two stuffing the comics into the bags, Hatfield waits till one of them isn't looking in the other man's direction, and then slaps him.
He is attempting to get the thugs to start fighting, so as soon as the unslapped person looks away from the previous target, Hatfield will slap them, too.
The slapped one starts looking around in total surprise, but few seconds later it seems he has deduced what is happening, then addresses to one of the brigands who is the most elegant of them all.
