This always bugs me when I watch The Dark Knight, so maybe someone can shine some light on it for me. In the garage battle near the beginning of the movie, Batman jumps onto the side of the Scarecrow's van and while hanging onto it, uses a wrist mounted thingamajig to rip a 6-12" tear in the skin of the van. What was the point of that? My theories are: (A) To induce a little terror: "The Bat is ripping my van apart, he's a monster!"; (B) He was just trying to hang onto the van and his device ripped the metal then snagged, instead of holding properly in place; or (C) He was actually trying to tear an opening to climb through, but he failed rather miserably. So what was it?
