^ I thought it seemed pointless too. Though, perhaps, it was just to show how far some people will go to be famous or get their names out there.
So the cop sabotaged the car? Could he be charged with any part of the murder? Even assuming he wasn't actively in cahoots with the two kids who actually killed the guy?
Perhaps as an accessory but it's pushing it? I haven't seen that part yet so I'm not entirely sure - plus my focus is on business law. With the sabotaged car you may be able to get attempted murder.
