Thank you. The thing I've written is only a first pitch on top of my head.
If someone subject you to violence then you have the right to defend yourself. It is implied. You should not initiate violence imply that you can use violence if you're not initiating it. If not my guide line would have said you should never use violence.
This doesn't solve all the resources problem but is a better system than the one we are currently under.
sounds sort of like this not so friendly experience...
