Kinda like Clint Eastwood in Gran Torino?
I don't think Walt would have handled or even put himself in this particular situation but I think you have the right idea. These men have lived their lives watching their once great country slowly slide into a despicable mire more horrible than their worst nightmares. What passes for virtue today makes their skin crawl, they seethe with quiet distain for the pathetic disregard today's youth have for the values that carried prior generations through America's toughest challenges. It must be all they can do to maintain their civility among the barbarians that now make up the bulk of "society". Who is to blame them if they are to cry foul and turn loose the dogs of war, certainly not me but most of them don't because they have the character it takes to hold their fire until the enemy is in their sights.
May we all follow their lead and stand together against the foe.
