Panos this is great! I love the comparison with the old police car....they have really improved!
In Argentina all street Policeman were suits and neck tie. Even in summer.... at least in Buenos Aires. I don't know about some other cities up north where it is a lo hotter.
As for the gunshot, I don't think they have one in the car, unless they are going to some special mission. They all carry beltguns.
The uniform here is exactly like the NY Police. Even the furry collar for the winter
