Someone robs the store, it could be a customer. It could be someone just window shopping. It could be a clerk embezzling. Elon doesn’t look at any videotape, but sends 22 year-old security guards who graduated from Ivy League schools into the store who arrest everybody and throws them all in jail, customers, clerks, and maybe one robber.
Then he realizes the store can’t open because there’s no clerks, and there’s nobody buying because there’s no customers. So a few days later, he lets out half the clerks and half the customers. That’s more like what he’s done.
