I was also reminded of Dirty Harry the day I heard about this thing.
Here's what I would do if I were supreme tyrant of the media:
Instead of giving this villain imposing epithets like "The Tarot Card Killer" and "Serial Sniper," which surely boost this guy's sense of self importance, everyone should start referring to him as "The Pansy Piece of Shit Fuckhead Who Murders The Unarmed." Because it's more accurate. If this guy is going to have a legacy, we could at least make it totally embarrasing.
