Jerry - the problem with the argument is that the punishment is always retrospective. If you shoot 20 people with your gun you will go to prison but 20 people will have lost their lives - if you hadn't been allowed the gun in the first place that would be far less likely to occur.
if a di*khead with a drone takes out a helo or an airliner, he will be traced and prosecuted but those crews/pax will still be dead.
