How does Superman solve this problem?
"Hmmm, let's see. 'Every piece of metal for 3 blocks around', that means this block & 3 blocks east, 3 blocks west, 3 blocks north and...Great Rao! I'm starting to see a pattern!! 3 blocks south. That's 49 square blocks of Metropolis!! I'll run to a nearby art supplies store and then ..."
"... paint every piece of metal in those 49 square blocks with enamel paint! That'll really piss people off."
Yup, folks, the Metropolis Marvel, the man with a Super-brain, just SPRAYPAINTED everyones car. And that includes the windows!! And how does Superman deal with local law enforcement? Yup, he thinks snarky things about them behind their backs. Way to go last son of Krypton. Too bad Jor-El didn't put the smart offspring into the rocket instead of you.
