Also I think he is in a good authority therefore he wears formal clothes.
He looks serious, I think it is because of his job.
Police officers are wearing gloves I think they are in a serious part of the job.
I infer that he is going to ride the car because they are standing on a street and there is a car behind them.
I predict that he is protecting lot because there are lots of police officers around him and they are looking serious too.
