This is very tragic for Rodger, but is irresponsibility at it best, both from the Friedkin Conservation and the pilot.
It is common knowledge that the war against poaching is a real WAR and these are well armed and organised groups.
To go up against them in a toy helicopter with no protection is foolhardy and inviting this sad outcome. Protective vests, a plate of ballistic protection in the seat and two pilots would be a minimum, and no need to be low level. Better still get a cheap camera/FLIR turret and sit at 1000 feet. Sorry, but this needs to be said. RIP
