The picture just doesn't provide enough information on the cyclists' riding practices, good or bad. That could easily be me, I always take the lane at stop lights/signs, because it prevents Right hooks when the light turns green and I'm more visible to others at the stop sign intersection. The OP mentioned that they ran the red light. That's not something I do, but in some areas it's ok, if they do it in a way that doesn't impede upon other road users.
