Pfffttttt! That would be against the law. AND, guess the dumbass thinks ALL weapons currently in use expel their empty casings?
Well, DUH, riktman, what does it take, Rocket science??? Just pass another law that requires all murderers to empty their revolvers of the expended brass and dump them on the floor at the crime scenes! Simple.
Why do I have to think of all these simple solutions to these problems???? An even better solution would be to require murderers to drop their driver’s licenses, or write their names on the walls at crime scenes. Another is to require them to register their intention with the police BEFORE the go kill their victims. Makes things SO much simpler.
HEY! We could require them to take out a murder permit! If they want to do a mass murder, they could get a government license, specifying the number of targets they want to take! If they exceed that number they could be fined; more revenue from fines. It would be a great source of progressive governmental income. My god am I a genius at solving these problems!! < /sarcasm>
