I still remember the spin they put on that after many Korean businesses were saved. "Americans shouldn't think they can do this Koreans have mandatory military service with a super tough boot camp". I respect the Koreans and did some training with their Marine Corps. They had their points but when it came to operating weaponry we were the masters, they were the pupils.
I dare say a lot of "shop keepers" remember the Korean's quite well and would do the same, but I must add there are not a lot of "shop keepers" in retail any more that aren't corporate chain stores. I doubt the employees of Kohls, Target, or Wal Mart are going to defend their stores with AK's and AR's. As I sit here and think about my retail areas around me - I can't think of an independent retailer other than maybe an "ACE" Hardware store which I know to be a franchise. I think the attitude will mirror that idiot at the beginning of that video - "free stuff man" and "I don't care" if its illegal. Riots in America would turn away from the political and into the "free stuff man" as quickly as they could.
