If a large arterial structure is hit , it can take upwards of 20-30sec to become so light headed and disorented to be out of the fight. I think sometimes we miss the actual understanding that shooting to stop, also incorperates shooting till the threat is removed or YOU REMOVE YOURSELF FROM THE THREAT. So now the question is do I have a good enough shot to get away from the bad guy, ( such as him becoming not able to chase you ) or do I have my family with me and have to fight it out till threat is dead. just my 2 pennies worth.
