Let's say you're walking out to the parking lot from i dunno, target, walmart or any store near you...you hear screaming and you then spot two people fighting, in this case the guy is beating the living hell out of his lady friend...WHAT would you do? (It could be the other way around of course)

Call 911 and get his license plate number.

Call 911 get his license plate number and then call The Courier or Comet for a reporter.

I would definitely call 911 and press down on my horn and bring as much attention to it as I could hoping to draw a crowd to open a can of whoop #%% upon him.

i would take my heaviest bag of groceries, like one with cans in it, and pop the sucker right in the back and then call 911 or vice versa, because i wouldn't stand there and watch some jack hit on a woman.

Call 911. Word.
