Did you do the right thing?
Without question in my opinion. Especially When you tried to evade them and get away and they still pursued you and your little girl. They were up to no good for sure and you did what you had to do to stop the threat. If you fired, that is another matter but drawing your weapon after what transpired was justified in most folks eyes. Who knows if they had a weapon or not and it really doesn't matter as they actually put you in fear of your life for no reason. You must defend yourself and especially your child. They are lucky that you didn't pull the trigger on your .45. I guarantee that they won't have the same approach again to other people without thinking this could happen again and someone else may just blow them away.........
Thank God you and your child were able to go home safely and in one piece.
