How are the CSI guys going to reconstruct this one? "Clearly, the car approached from the west, passed the victims, made an illegal U-turn, and shot the victims. Then the vehicle pulled another U-turn, and drove off to the east."
"Wait a minute Lieutenant. Don't be so sure. The victims could have disapparated across the street just before they were shot, and then disapparated back across the street as the car drove away."
"Disapparated? Like in Harry Potter? That would be hard to do wouldn't it, if you'd been shot?"
"Maybe they used a portkey?"
