The angle makes it hard to tell but Tamira is shooting at Braxton. That little shield is manifesting because of the bullets hitting it. It's easier to see in the next panel that shows it.

Personally I'd shoot the wizard before the brute baddie. Smaller health bar to deplete. :) Oh and I hope the story doesn't forget about the police partner lady or the other victims.
