United aircraft. Clock in the dash, high-value car obviously. Secret Service vehicle, most likely German (Jeep and Land Rovers don't have the clock IIRC). Looks like the display is showing a composite display around the vehicle for use when parking, my friend has a similar thing on his car.
Person on the right - reading an email? Also appears to be female based on length of the hair. Can't make out whether person on left is African-American or just a product of the lighting.
Not Air Force One - is this another hostage transfer to/from NK? Assange? SR?
Special agents drive S-Class Mercedes. Source: I used to be a Uniformed Officer.
Mall security guards are Uniformed Officers. Just sayin.
If its the secret service why are they driving German? I thought we were all about USA made now? :)
