black and white Banksy-style stencil on a white wall in an art gallery

black and white Banksy-style stencil on a white wall in an art gallery. The stencil depicts a figure wearing judicial robes and wig, wielding a gavel above his head. Beneath him, another figure is on the ground, apparently being attacked. This figure holds up a sign with a red mark on it, possibly representing blood. The camera pans out to reveal the stencil on the wall of a hallway in the gallery, with framed paintings visible in the background. The floor is a dark, smooth surface. The lighting is dim but focused on the stencil.
