It's not the best of photos, but it proves the point. I took this photo of a private security guard, heavily armed and aiming his assault rifle at the entrance of Woolworths. If that should fail, he has an automatic pistol. Perhaps that is a stun grenade at his left shoulder. A customer is walking past. OBSERVATION: It seems one can't trust the customers too much these days. When this started in South Africa, such security guards were discreet. That may not be the case any more, as one sees here. What is happening here is a transfer of cash out of the store. Such photos are not advised.
