The video looks like the owner is Muslim from Pakistan or Arabia. The robbers could be Amish or Mennonite most likely
A significant number of shopkeepers in Detroit are Chaldean.
The guy is Chaldean, they're the only people with guts enough to own party stores in Detroit. And for what it's worth, they own most of the party stores and gas stations in the communities outside of Detroit too. They work hard and usually employ all their family members too.
I've been getting my gasoline from the same Chaldean owned BP station by my house for the past 11 years. I know the owner, his wife and all the kids and they would do anything for me. Whenever I enter the store it's alwas "Hi Mr. Don, how are you doing".....They're a great family and almost every weekend they're letting some school or church kids conduct a car wash on the lot.
