Greatwater Lake Since when is stealing a crime?

Khaba's signal had been clear. Step back. Give the intruder a chance to live another day.
But when the stranger spoke, sweet and pleasant as if nothing had happened with wanting eyes locked on her and her fellow women, it became a matter moreso of defending herself. 
She steps in front of Selena, gently shoving her aside with a pointy shoulder. Jaws snap as a lunge for his face is made, eyes of fire burning and wide as saucers, a ribbon of saliva dripping from an ochre chin. She does not make contact just yet, though she comes dangerously close. Tail stiff and raised high above her back, she makes her attempt to herd him closer to the border. Get out. 
He had one last chance to leave of his own free will.
