As bad as the Conservative government's crime reform agenda is and has been, there is one bright spot that I think should be noted. The Conservatives are planning on altering the criminal code to allow greater discretion for the individual to defend himself or herself against an aggressor.
As things stand now it is deeply ambiguous who would get in more trouble. The person that tried to rob you, or you for punching out the person who tried to rob you. Correcting this, and freeing the individual to defend his or her own self and property is an important positive move.
