Yes, my scenario says that the bullet first hits the guardrail just to the right of dark T Shirt man and shatters on impact. Then, where the spray of bullet fragments, aka schrapnel go, depends on exactly where the bullet hits. If it is on the vertical pipe and just at the right point of impact, then it’s possible that the shattered pieces of the bullet would ricochet at some angle that would hit Dutch and dark T Shirt man.
I assume this is the case since dark T Shirt man raises his hand to his right side, and Dutch spins to his left and ducks. Just before the bullet hits the guardrail, it looks like dark T Shirt man is just a bit farther away from the Megatron than Dutch which allow both men to be hit with schrapnel.
I’m convinced that Dutch’s injury is not a bullet wound since he walks down the steps on his own and there is no blood visible.
