Considering the alternative is dying I'll take my chances in court.
If I carry after drinking and my life is not threatened then I will not be in court; assuming I have not violated any laws. If I don't carry after drinking and my life is threatened, I might die then I will not be in court. The only time I would be in court is if I am alive after having successfully defending my life. The same can happen in the home, does this mean one should lock all firearms away after having a drink, and simply hope it will be ok? This is a fallacy promoted by two groups those against alcohol consumption and those against carrying firearms. The reasons are simple and easy to discern so I'll leave that to the readers for now.
