Re: The Official: Hayley Atwell as Peggy Carter Thread.
If it's a vibranium shield(and she knows this) then there ain't gonna be ricochet's. The bullets would simply lose all their momentum and drop to the ground. She is definitely shooting at the shield rather than Steve. Seems very much like what she's doing is telling Steve and the other officer there "Hey, I know this is 1943 and I'm a woman and this is the military and all that but I will not be patronized" in a manner that doesn't require much obvious dialogue for them to get the point.
You know, it occurs to me that Captain America is basically the superhero equivalent of Mary Poppins. Practically perfect in every way and all that stuff.
