Observe the following excerpt from the Criminal Code of Canada, taken from <a href=http://everything2.com/index.pl?node_id=1190385> here</a>:

35. Every one who has without justification assaulted another but did not commence the assault with intent to cause death or grievous bodily harm, or has without justification provoked an assault on himself by another, may justify the use of force subsequent to the assault if
(a) he uses the force

So basically, Jedi are allowed to commit senseless acts of violence?
