Getting family out of the way and to safety is not running away and hiding ,its saving lives ,the same applies if you usher and help any vulnerable people to safety ,your helping ,doing something useful ,what I,m trying to say is in the absence of the professionals ,you do what you can as a man ,whether its getting people safe ,tending the wounded ,throwing stones or impeding the attacker in any way you can ,you do it ! Once the armed police arrive obviously you make yourself useful by getting g out of their way .
