What would you expect the punishment to be for causing "Death by careless driving"? Well, as long as you "only" kill a biker, then you may be surprised.
"Killick, 25, was disqualified from driving for 12 months and given a 12-month community order during which he will have to complete 150 hours of unpaid work."
So if you want to kill someone, do not shoot them. Do not hire a hitman. Just befriend them. Get them to take their test. Then RUN THEM OVER.
