Jesus wept, it's so frustratingly obvious that anytime some flavor of cop kills someone, the news media reporting (if any) will be this weird Yoda grammar pidgin.
The femoidically gendered female shot with its gun by very personally pulling the trigger, with this viscerally physical action performed by the said femalian in most pointedly concrete terms amounting to it (the femaloidistical entity, a specimen of the species known as females) firing lethal gunshots at the border patrol with the female's own two hands.
Subsequently return fire manifested itself from somewhere and came into contact with the female suspect female. The Justice Enforcement Officers involved in the situation were made a part of a bilateral exchange of gunfire between the shooting female and the officers situated in the scenario in which shooting was, to some extent, quite possibly performed from their side as well.
