Yes, so the penalty will have to be very harsh for doing that, it's nearly as bad as gun ownership.
It's the rocks I'm worried about. England's full of rocks, and a rock can be used to kill someone. Murders have been committed with rocks since the Stone Age, and an irresponsible person with a rock can really hurt someone. I would recommend banning all rocks except that England itself is a huge rock. What to do, what to do?
What the Brits need are cops with guns and the right to use them like in the US.
