The differences between shooting someone and stabbing someone is very large in many ways more then one, the few differences is that shooting someone is easy, you aim and pull the trigger, the person drops, any idiot can do this, the person being shot has little chance to defend himself or do anything to defend himself unless he is lucky enough to find cover in time, through if someone is taking aim at you, it is already too late. Now, take a guy with a knife, the person has a lot more chance to defend themselves, they also a have higher chance of seeing their attacker to allow them to escape or defend themselves, they can also attack back, how can you attack someone with a gun aimed at you? (other then being armed with a gun as well) it's the old catch phase... move and your dead... Also, it takes a lot more "guts" to say to stab someone with a knife then it does then to pull the trigger, you also need to be pretty strong or crazy enough to walk up to a person and stab them.
