The Dark Knight Rises Sewer Fight unprofessional

Since I'm studying Law Enforcement and I train in combatives. They teach you going hand to hand is the last resort.

Bruce Wayne has thousands of dollars in gear and the first thing he does is get into a brawl with a man who is well trained and in great shape. i know he uses the flashbangs, but its a little too late by then.

its really the only thing that bugged me. But watching Wayne getting served for his mistake was the coolest thing I seen in theaters.
