own property.? okay we agree that if someone robs you with a knife, and you have a gun and shoot them. you would get into trouble because you did not use equal or lesser force to stop him. but, i said someone had a bowie knife(person robbed) and someone had a switchblade (robber). since they are both knives would the force be considered equal, he said no ? BTW: yes, i already know this is a stupid question but i would like to know if i was right, i can't find the answer online.
