HB 2615 simply states that if a criminal breaks into your home, your occupied vehicle or your place of business, you may presume he is there to do bodily harm and you may use any force necessary against him.  It also removes the "duty to retreat" if you are attacked in any place you have a legal right to be. 

Further, HB 2615 provides protection from criminal prosecution and civil litigation for those who defend themselves from criminal attack.  The "Castle Doctrine" bill met with overwhelming, bipartisan support, passing 96-2 in the state House and 83-4 in the Senate.  Oklahoma joins eight other states that have signed similar legislation into law this legislative cycle.
