Allen Zhang directed the two to work in cooperation.
The two immediately agreed, as there was no problem with that.
As for what Allen Zhang himself should do?
He was just an ordinary Los Angeles five-star good citizen.
If he didn't want to be taken to the police station for an identity check, it was better to slip away first and be a bystander; what happened next had nothing to do with him.
Dominic also knew that Allen Zhang was an undocumented non-citizen and it was not good to show off in front of the police, so he asked him for the video to keep it and immediately called the 911 emergency number on his mobile phone.
"Hello, this is the 911 Southern Branch. What's the situation on your end?" the dispatcher at the Southern Branch asked as she answered the call.
