Who is the cop on bridge in dark knight rises who telling them not to come any closer?

You are likely referring to the scene in *The Dark Knight Rises* where Batman and Bane are facing off on the bridge, and a Gotham City Police Officer tries to intervene. This officer is not named in the film, and is not a character with any significant role in the story.

It's important to note that the officer is not just telling them "not to come any closer" but warns them to "stand down" and "disperse". This is a common tactic used by law enforcement to try and de-escalate a dangerous situation.

The scene emphasizes the futility of the police's attempts to stop the two powerful figures, highlighting the chaos and desperation in Gotham.
