4) Time. The entire attack, from the time the first child was shot until the shooter killed himself, lasted less than three minutes. Think about that for a second. You don’t have much time to act. Don’t expect the police to be able to arrive in time to save you. You won’t be able to get to your vehicle glove compartment to get the gun you don’t carry “because it’s too heavy.” You are on your own and will be forced to use whatever gear you have on your person to stop this kind of attack.
