There are many ways to verify addresses. There don’t seem to be any excuses for mistakes of this sort.
I suppose the police don’t have GPS? I know it is a new fangled thing and you could hardly expect the police / DEA to PLAN a raid before they execute it, you know, using accurate maps (Google Earth comes to mind) and all the things that all the rest of us do as a matter of routine in executing the weekly shopping list. Noooo! They are too professional for any of that.
