The jury deciding the fate of Buffalo Police Officer Corey Krug learned about two different cops Thursday.

The first, a veteran lawman with more than a thousand arrests, a patrol officer known for working the toughest neighborhoods and meanest streets.

The other, a cop who inflicts pain and draws blood.

"When the defendant gets mad, he comes out swinging," Assistant U.S. Attorney John D. Fabian told the jury Thursday. "That's his M.O. and you see it time and again and again and again."

Accused of using excessive force on three separate occasions dating back to 2010, Krug, an 18-year veteran of the force, claims the evidence against him is full of holes.

"This case fails miserably," defense lawyer Terrence M. Connors told jurors. "This case they brought you is a patchwork of inconsistencies."

Connors pointed to civil lawsuits filed by the three men allegedly assaulted by Krug, and suggested they were motivated to exaggerate, even lie, about what he did to them.

He started with Devin Ford, the Lackawanna man who crossed paths with Krug on Thanksgiving Day morning in 2014 on Chippewa Street. A WKBW-TV video of the incident led to an FBI investigation and the current criminal prosecution.
